# High-Agency Frontend Skill

<!-- BEGIN: Tier-1 Reference Canon + claude.ai/design Taste Engine (OmegaOS design doctrine) -->

## 0. NORTH STAR — Tier-1 Reference Canon & the claude.ai/design Taste Engine

Default output must read as a **Linear/Vercel-tier clone, not a generic Tailwind template**. The bar is `linear.app` and the 19-site canon; anything that reads "default shadcn / bootstrap / stock SaaS" has FAILED and must be raised, not shipped.

- Pass test: one accent + hairline structure + tight negative display tracking + dark-first (or fully-themed) depth + motion restraint — a designer should not be able to tell it apart from a Tier-1 reference at a glance.
- Pick ONE coherent dialect (a temperature + one or two signature deviations) and commit; never blend three sites' accents into a soup.
- Steal verified discipline, not hex blindly — never invent false precision (a curve/token a site does not actually ship).
- When unsure, return to the canon and measure against the Anchor before calling it done.

### Default taste engine — distilled from claude.ai/design + the Linear-tier canon

Apply these unless the user overrides — a contrary brief wins, but absence of one does not; fall back to these defaults:

1. **Restraint is the feature.** Default to LESS — one accent, one type family, few elements per section. Suppress motion on high-frequency surfaces (nav hover, keyboard actions) entirely. If a flourish doesn't earn its place, cut it. The most-copied trait of every canon site is what they left out.
2. **Single-accent color discipline.** Exactly ONE accent hue carries brand + CTAs + focus; everything else is a neutral ramp. Reserve any second/third color for *state* (success/error) or *data*, never decoration. A near-black or near-white never goes pure `#000`/`#FFF`.
3. **Warmth or cool — pick a temperature and commit.** Choose ONE: cool (Linear indigo, Vercel blue, neutral-blue-black) OR warm (claude.ai cream + terracotta, Railway violet, PlanetScale/orange). Build the *entire* neutral ramp to match it (claude.ai runs warm ivory + warm-charcoal, never blue-black). Never mix warm and cool grays in one project.
4. **Typographic confidence via weight + size + tracking, not theatrics.** Display ≤600 weight (whisper, never 800-black). Apply size-proportional NEGATIVE tracking on large display (~-.02 to -.05em), neutral on body; the only positive tracking is a small uppercase eyebrow. Body never below ~14px. A neutral grotesk is the floor; a serif body (claude.ai) or a mono-as-second-voice (Vercel/PlanetScale/Oxide) is the anti-generic signature — never default to bare Inter for premium.
5. **Hairline structure over heavy chrome.** Build with 1px (or .5px) borders — solid neutral, or translucent white/black over a dark canvas so edges *glow* rather than cut. Snap everything to a 4px spacing ladder with a generous fixed section beat (~96px), cap content width (~1200–1280px), and keep a consistent small radius ladder (4/8/12px; pills only for chips/toggles).
6. **Depth from surface + light, not drop-shadow glow.** Prefer a near-black surface ladder + hairlines (Linear), a single colored glow/ring (Neon's 1px green ring, Clerk's halo), or a soft tinted shadow (claude.ai composer) — never a generic gray box-shadow or the "AI purple" neon glow. Ban shadow-glow as the default depth cue.
7. **Motion discipline — short, eased, purposeful.** Animate only `transform`/`opacity`. Keep interactive transitions snappy (treat ~150–200ms as a target, verify on the real site — don't assert a curve a site never ships). One easing family per project; differentiate reveals by staggered DELAY, not by switching curves. Reserve longer/ambient motion for one hero centerpiece. No bounce on chrome, no parallax-by-default, no scroll-jacking.
8. **Dark-first depth as a first-class mode (and a real light mode).** Default to a dark or dark-capable canvas with the surface-ladder/glow depth language; if light-first (Clerk/cal.com/WorkOS/claude.ai light), ship BOTH modes via a token swap — never leave a half-built theme.
9. **Craft in the details — keyboard-first, honest content.** Real `:focus-visible` rings (token-tinted, with offset), tactile press states (`active:scale`/`translate-y`), branded `::selection`, IDE-tokenized inline code. Show real artifacts (actual config, real metrics) over stock imagery; no emojis, no filler chrome ("scroll to explore"), no fake round numbers.
10. **The clone test as the bar.** Output should be indistinguishable from a Tier-1 site (Linear/Vercel-tier): one accent, hairline structure, tight tracking, dark-first depth, motion restraint. "Generic Tailwind template" is a failure state — raise it until it reads canon.

### The canonical reference set — anchor = linear.app

Build to this bar by default; the output should sit beside these.

**Anchor**
- **linear.app** — steal: near-black `#08090A` canvas, ONE desaturated indigo `#5e6ad2`, Inter at weight ≤600 with size-proportional NEGATIVE tracking, depth from a surface-ladder + 1px hairlines (NEVER shadow-glow), 96px section beat on a 4px grid, motion that suppresses itself on high-frequency surfaces.

**Tier 1 — Quasi-identical to Linear**
- **vercel.com** — steal: Geist Sans + Geist Mono, pure `#000` / `#EDEDED` mono palette, ONE blue `#0070F3` as punctuation, hairline `rgba(255,255,255,.08)` cards, and the morphing shared-layout nav (sliding pill + resizing panel).
- **planetscale.com** — steal: ZERO custom fonts (body in system MONO, sans is the exception), WARM orange `#f35815`, sharp 0-radius boxes via the dashed-box border + ASCII diagrams, and hover color-swaps that are 0ms instant.
- **railway.app** — steal: IBM Plex Serif display (weight 500) over Inter body, VIOLET-tinted neutrals (hue 246), magenta→violet accent (`ring-pink-700`, CTA `#aa0aaa→#381dbd`), glow-grows-not-box CTA, blueprint-grid hairlines, and the live split-flap board.
- **resend.com** — steal: Domaine + ABC Favorit display, achromatic Radix-gray on `#000` with NO solid accent — color exists only as a traveling glow on a 1px divider; IDE-token inline code.
- **cal.com** — steal: Cal Sans display (POSITIVE tracking on small subheads) + Inter body, grayscale-as-brand (theme-flipping near-black `#111827` ↔ white CTA), 4px radius, graded per-state button shadows, branded `::selection`.

**Tier 2 — Same energy**
- **clerk.com** — steal: Suisse Int'l, body floor 15px, LIGHT-first with a warm violet primary `#6c47ff` + cyan `#5de3ff` demoted to a four-stop glow halo, .5px+1px hairlines with inset-rim shadows.
- **trigger.dev** — steal: Satoshi titles + Geist UI + Geist Mono, ONE acid-lime `#a8ff53` (with a real lavender `#7655fd` second accent) on bespoke cool-charcoal, ONE easing only, and the `moving-lines` diagonal card-hover.
- **turso.tech** — steal: Inter display at `-.03em`, Bunker-black `#0D1318` + mint Turso Aqua `#4FF8D2`, aqua-FILL/BLACK-text CTA, fuchsia second accent, hairline-flip-to-aqua hovers, near-invisible 5%-opacity light dot-grid.
- **outstatic.com** — steal: a giant `leading-[0.9]` SERIF hero + one achromatic gradient-clipped word, light-first monochrome zinc, full-bleed SVG line-bg layers, and the neo-brutalist hard-offset-shadow push button.
- **supabase.com** — steal: Circular Std at weight 500 (default tracking, NOT tight), 0°-saturation grayscale lit by ONE emerald `#3ECF8E` (green = success), neutral-gradient hairline cards, framer/anime/gsap motion at 400ms.
- **neon.tech** — steal: one-weight custom display ("esbuild") + Inter + GeistMono, pure-black + mint `#00e599` shipped as a full alpha ladder, a 1px green RING instead of a drop-shadow on hover, 10%-green bloom gradients.

**Tier 3 — A cut above on craft**
- **liveblocks.io** — steal: Suisse Intl with JetBrains-Mono eyebrows, translucent-white hairlines (`#fdfcfc21`) that GLOW over `#000`, a multi-channel per-product semantic accent system locked to one lightness band, and CSS mask-sweep reveals.
- **basehub.com** — steal: Geist + Geist Mono (by Geist's makers), pure-gray near-black `#040404` + warm orange `#FF6C02`, a five-layer rgba-orange ember glow as a scroll-progress pin, per-character 3D sin()-staggered list tumble.
- **basement.studio** — steal: Geist Sans + flauta display on TRUE-black brutalism, loud per-case-study accents (`#ff4d00`/`#00FF9B`), translucent `white/.2` + `#2E2E2E` hairlines, and the `steps()` frame-stepped sprite mask reveal.
- **rauno.me** — steal: a private bespoke face at tiny 14px, PURE-achromatic `hsl(0 0% N%)` neutrals, matte soft `0.12`-alpha shadows (no glow), a bounded OS-desktop canvas, and the hand-built right-edge minimap navigator.

**Tier 4 — Style-defining**
- **oxide.computer** — steal: SuisseIntl + a custom GT America Mono that DRAWS live ASCII diagrams, color authored in OKLCH (cool-black `oklch(0.162 0.01 260)` + oxide-green `≈#00D889`, green=success), one unified stroke token for all 1px edges, low-bounce Framer springs.
- **workos.com** — steal: Untitled Sans with `-.05em→-.07em` display tracking, light↔dark-navy sandwich, indigo `#6363f1` primary + a saturated spectrum reserved for the signature stacked-RGBA chromatic glow; pill buttons, 1px hairlines.
- **claude.ai** — steal: warm-cream ivory canvas (`#faf9f5`, never cold gray), a single terracotta `#d97757` accent, longform body in a SERIF (anti-AI-slop), soft drop-shadow depth over hairlines, token-streaming text as the signature motion.

<!-- END: Tier-1 Reference Canon + claude.ai/design Taste Engine -->

## 1. ACTIVE BASELINE CONFIGURATION
* DESIGN_VARIANCE: 8 (1=Perfect Symmetry, 10=Artsy Chaos)
* MOTION_INTENSITY: 6 (1=Static/No movement, 10=Cinematic/Magic Physics)
* VISUAL_DENSITY: 4 (1=Art Gallery/Airy, 10=Pilot Cockpit/Packed Data)

**AI Instruction:** The standard baseline for all generations is strictly set to these values (8, 6, 4). Do not ask the user to edit this file. Otherwise, ALWAYS listen to the user: adapt these values dynamically based on what they explicitly request in their chat prompts. Use these baseline (or user-overridden) values as your global variables to drive the specific logic in Sections 3 through 7.

## 2. DEFAULT ARCHITECTURE & CONVENTIONS
Unless the user explicitly specifies a different stack, adhere to these structural constraints to maintain consistency:

* **DEPENDENCY VERIFICATION [MANDATORY]:** Before importing ANY 3rd party library (e.g. `framer-motion`, `lucide-react`, `zustand`), you MUST check `package.json`. If the package is missing, you MUST output the installation command (e.g. `npm install package-name`) before providing the code. **Never** assume a library exists.
* **Framework & Interactivity:** React or Next.js. Default to Server Components (`RSC`). 
    * **RSC SAFETY:** Global state works ONLY in Client Components. In Next.js, wrap providers in a `"use client"` component.
    * **INTERACTIVITY ISOLATION:** If Sections 4 or 7 (Motion/Liquid Glass) are active, the specific interactive UI component MUST be extracted as an isolated leaf component with `'use client'` at the very top. Server Components must exclusively render static layouts.
* **State Management:** Use local `useState`/`useReducer` for isolated UI. Use global state strictly for deep prop-drilling avoidance.
* **Styling Policy:** Use Tailwind CSS (v3/v4) for 90% of styling. 
    * **TAILWIND VERSION LOCK:** Check `package.json` first. Do not use v4 syntax in v3 projects. 
    * **T4 CONFIG GUARD:** For v4, do NOT use `tailwindcss` plugin in `postcss.config.js`. Use `@tailwindcss/postcss` or the Vite plugin.
* **ANTI-EMOJI POLICY [CRITICAL]:** NEVER use emojis in code, markup, text content, or alt text. Replace symbols with high-quality icons (Radix, Phosphor) or clean SVG primitives. Emojis are BANNED.
* **Responsiveness & Spacing:**
  * Standardize breakpoints (`sm`, `md`, `lg`, `xl`).
  * Contain page layouts using `max-w-[1400px] mx-auto` or `max-w-7xl`.
  * **Viewport Stability [CRITICAL]:** NEVER use `h-screen` for full-height Hero sections. ALWAYS use `min-h-[100dvh]` to prevent catastrophic layout jumping on mobile browsers (iOS Safari).
  * **Grid over Flex-Math:** NEVER use complex flexbox percentage math (`w-[calc(33%-1rem)]`). ALWAYS use CSS Grid (`grid grid-cols-1 md:grid-cols-3 gap-6`) for reliable structures.
* **Icons:** You MUST use exactly `@phosphor-icons/react` or `@radix-ui/react-icons` as the import paths (check installed version). Standardize `strokeWidth` globally (e.g., exclusively use `1.5` or `2.0`).


## 3. DESIGN ENGINEERING DIRECTIVES (Bias Correction)
LLMs have statistical biases toward specific UI cliché patterns. Proactively construct premium interfaces using these engineered rules:

**Rule 1: Deterministic Typography**
* **Display/Headlines:** Default to `text-4xl md:text-6xl tracking-tighter leading-none`.
    * **ANTI-SLOP:** Discourage `Inter` for "Premium" or "Creative" vibes. Force unique character using `Geist`, `Outfit`, `Cabinet Grotesk`, or `Satoshi`.
    * **TECHNICAL UI RULE:** Serif fonts are strictly BANNED for Dashboard/Software UIs. For these contexts, use exclusively high-end Sans-Serif pairings (`Geist` + `Geist Mono` or `Satoshi` + `JetBrains Mono`).
* **Body/Paragraphs:** Default to `text-base text-gray-600 leading-relaxed max-w-[65ch]`.

**Rule 2: Color Calibration**
* **Constraint:** Max 1 Accent Color. Saturation < 80%.
* **THE LILA BAN:** The "AI Purple/Blue" aesthetic is strictly BANNED. No purple button glows, no neon gradients. Use absolute neutral bases (Zinc/Slate) with high-contrast, singular accents (e.g. Emerald, Electric Blue, or Deep Rose).
* **COLOR CONSISTENCY:** Stick to one palette for the entire output. Do not fluctuate between warm and cool grays within the same project.

**Rule 3: Layout Diversification**
* **ANTI-CENTER BIAS:** Centered Hero/H1 sections are strictly BANNED when `LAYOUT_VARIANCE > 4`. Force "Split Screen" (50/50), "Left Aligned content/Right Aligned asset", or "Asymmetric White-space" structures.

**Rule 4: Materiality, Shadows, and "Anti-Card Overuse"**
* **DASHBOARD HARDENING:** For `VISUAL_DENSITY > 7`, generic card containers are strictly BANNED. Use logic-grouping via `border-t`, `divide-y`, or purely negative space. Data metrics should breathe without being boxed in unless elevation (z-index) is functionally required.
* **Execution:** Use cards ONLY when elevation communicates hierarchy. When a shadow is used, tint it to the background hue.

**Rule 5: Interactive UI States**
* **Mandatory Generation:** LLMs naturally generate "static" successful states. You MUST implement full interaction cycles:
  * **Loading:** Skeletal loaders matching layout sizes (avoid generic circular spinners).
  * **Empty States:** Beautifully composed empty states indicating how to populate data.
  * **Error States:** Clear, inline error reporting (e.g., forms).
  * **Tactile Feedback:** On `:active`, use `-translate-y-[1px]` or `scale-[0.98]` to simulate a physical push indicating success/action.

**Rule 6: Data & Form Patterns**
* **Forms:** Label MUST sit above input. Helper text is optional but should exist in markup. Error text below input. Use a standard `gap-2` for input blocks.

## 4. CREATIVE PROACTIVITY (Anti-Slop Implementation)
To actively combat generic AI designs, systematically implement these high-end coding concepts as your baseline:
* **"Liquid Glass" Refraction:** When glassmorphism is needed, go beyond `backdrop-blur`. Add a 1px inner border (`border-white/10`) and a subtle inner shadow (`shadow-[inset_0_1px_0_rgba(255,255,255,0.1)]`) to simulate physical edge refraction.
* **Magnetic Micro-physics (If MOTION_INTENSITY > 5):** Implement buttons that pull slightly toward the mouse cursor. **CRITICAL:** NEVER use React `useState` for magnetic hover or continuous animations. Use EXCLUSIVELY Framer Motion's `useMotionValue` and `useTransform` outside the React render cycle to prevent performance collapse on mobile.
* **Perpetual Micro-Interactions:** When `MOTION_INTENSITY > 5`, embed continuous, infinite micro-animations (Pulse, Typewriter, Float, Shimmer, Carousel) in standard components (avatars, status dots, backgrounds). Apply premium Spring Physics (`type: "spring", stiffness: 100, damping: 20`) to all interactive elements—no linear easing.
* **Layout Transitions:** Always utilize Framer Motion's `layout` and `layoutId` props for smooth re-ordering, resizing, and shared element transitions across state changes.
* **Staggered Orchestration:** Do not mount lists or grids instantly. Use `staggerChildren` (Framer) or CSS cascade (`animation-delay: calc(var(--index) * 100ms)`) to create sequential waterfall reveals. **CRITICAL:** For `staggerChildren`, the Parent (`variants`) and Children MUST reside in the identical Client Component tree. If data is fetched asynchronously, pass the data as props into a centralized Parent Motion wrapper.

## 5. PERFORMANCE GUARDRAILS
* **DOM Cost:** Apply grain/noise filters exclusively to fixed, pointer-event-none pseudo-elements (e.g., `fixed inset-0 z-50 pointer-events-none`) and NEVER to scrolling containers to prevent continuous GPU repaints and mobile performance degradation.
* **Hardware Acceleration:** Never animate `top`, `left`, `width`, or `height`. Animate exclusively via `transform` and `opacity`.
* **Z-Index Restraint:** NEVER spam arbitrary `z-50` or `z-10` unprompted. Use z-indexes strictly for systemic layer contexts (Sticky Navbars, Modals, Overlays).

## 6. TECHNICAL REFERENCE (Dial Definitions)

### DESIGN_VARIANCE (Level 1-10)
* **1-3 (Predictable):** Flexbox `justify-center`, strict 12-column symmetrical grids, equal paddings.
* **4-7 (Offset):** Use `margin-top: -2rem` overlapping, varied image aspect ratios (e.g., 4:3 next to 16:9), left-aligned headers over center-aligned data.
* **8-10 (Asymmetric):** Masonry layouts, CSS Grid with fractional units (e.g., `grid-template-columns: 2fr 1fr 1fr`), massive empty zones (`padding-left: 20vw`). 
* **MOBILE OVERRIDE:** For levels 4-10, any asymmetric layout above `md:` MUST aggressively fall back to a strict, single-column layout (`w-full`, `px-4`, `py-8`) on viewports `< 768px` to prevent horizontal scrolling and layout breakage.

### MOTION_INTENSITY (Level 1-10)
* **1-3 (Static):** No automatic animations. CSS `:hover` and `:active` states only.
* **4-7 (Fluid CSS):** Use `transition: all 0.3s cubic-bezier(0.16, 1, 0.3, 1)`. Use `animation-delay` cascades for load-ins. Focus strictly on `transform` and `opacity`. Use `will-change: transform` sparingly.
* **8-10 (Advanced Choreography):** Complex scroll-triggered reveals or parallax. Use Framer Motion hooks. NEVER use `window.addEventListener('scroll')`.

### VISUAL_DENSITY (Level 1-10)
* **1-3 (Art Gallery Mode):** Lots of white space. Huge section gaps. Everything feels very expensive and clean.
* **4-7 (Daily App Mode):** Normal spacing for standard web apps.
* **8-10 (Cockpit Mode):** Tiny paddings. No card boxes; just 1px lines to separate data. Everything is packed. **Mandatory:** Use Monospace (`font-mono`) for all numbers.

## 7. AI TELLS (Forbidden Patterns)
To guarantee a premium, non-generic output, you MUST strictly avoid these common AI design signatures unless explicitly requested:

### Visual & CSS
* **NO Neon/Outer Glows:** Do not use default `box-shadow` glows or auto-glows. Use inner borders or subtle tinted shadows.
* **NO Pure Black:** Never use `#000000`. Use Off-Black, Zinc-950, or Charcoal.
* **NO Oversaturated Accents:** Desaturate accents to blend elegantly with neutrals.
* **NO Excessive Gradient Text:** Do not use text-fill gradients for large headers.
* **NO Custom Mouse Cursors:** They are outdated and ruin performance/accessibility.

### Typography
* **NO Inter Font:** Banned. Use `Geist`, `Outfit`, `Cabinet Grotesk`, or `Satoshi`.
* **NO Oversized H1s:** The first heading should not scream. Control hierarchy with weight and color, not just massive scale.
* **Serif Constraints:** Use Serif fonts ONLY for creative/editorial designs. **NEVER** use Serif on clean Dashboards.

### Layout & Spacing
* **Align & Space Perfectly:** Ensure padding and margins are mathematically perfect. Avoid floating elements with awkward gaps.
* **NO 3-Column Card Layouts:** The generic "3 equal cards horizontally" feature row is BANNED. Use a 2-column Zig-Zag, asymmetric grid, or horizontal scrolling approach instead.

### Content & Data (The "Jane Doe" Effect)
* **NO Generic Names:** "John Doe", "Sarah Chan", or "Jack Su" are banned. Use highly creative, realistic-sounding names.
* **NO Generic Avatars:** DO NOT use standard SVG "egg" or Lucide user icons for avatars. Use creative, believable photo placeholders or specific styling.
* **NO Fake Numbers:** Avoid predictable outputs like `99.99%`, `50%`, or basic phone numbers (`1234567`). Use organic, messy data (`47.2%`, `+1 (312) 847-1928`).
* **NO Startup Slop Names:** "Acme", "Nexus", "SmartFlow". Invent premium, contextual brand names.
* **NO Filler Words:** Avoid AI copywriting clichés like "Elevate", "Seamless", "Unleash", or "Next-Gen". Use concrete verbs.

### External Resources & Components
* **NO Broken Unsplash Links:** Do not use Unsplash. Use absolute, reliable placeholders like `https://picsum.photos/seed/{random_string}/800/600` or SVG UI Avatars.
* **shadcn/ui Customization:** You may use `shadcn/ui`, but NEVER in its generic default state. You MUST customize the radii, colors, and shadows to match the high-end project aesthetic.
* **Production-Ready Cleanliness:** Code must be extremely clean, visually striking, memorable, and meticulously refined in every detail.

## 8. THE CREATIVE ARSENAL (High-End Inspiration)
Do not default to generic UI. Pull from this library of advanced concepts to ensure the output is visually striking and memorable. When appropriate, leverage **GSAP (ScrollTrigger/Parallax)** for complex scrolltelling or **ThreeJS/WebGL** for 3D/Canvas animations, rather than basic CSS motion. **CRITICAL:** Never mix GSAP/ThreeJS with Framer Motion in the same component tree. Default to Framer Motion for UI/Bento interactions. Use GSAP/ThreeJS EXCLUSIVELY for isolated full-page scrolltelling or canvas backgrounds, wrapped in strict useEffect cleanup blocks.

### The Standard Hero Paradigm
* Stop doing centered text over a dark image. Try asymmetric Hero sections: Text cleanly aligned to the left or right. The background should feature a high-quality, relevant image with a subtle stylistic fade (darkening or lightening gracefully into the background color depending on if it is Light or Dark mode).

### Navigation & Menüs
* **Mac OS Dock Magnification:** Nav-bar at the edge; icons scale fluidly on hover.
* **Magnetic Button:** Buttons that physically pull toward the cursor.
* **Gooey Menu:** Sub-items detach from the main button like a viscous liquid.
* **Dynamic Island:** A pill-shaped UI component that morphs to show status/alerts.
* **Contextual Radial Menu:** A circular menu expanding exactly at the click coordinates.
* **Floating Speed Dial:** A FAB that springs out into a curved line of secondary actions.
* **Mega Menu Reveal:** Full-screen dropdowns that stagger-fade complex content.

### Layout & Grids
* **Bento Grid:** Asymmetric, tile-based grouping (e.g., Apple Control Center).
* **Masonry Layout:** Staggered grid without fixed row heights (e.g., Pinterest).
* **Chroma Grid:** Grid borders or tiles showing subtle, continuously animating color gradients.
* **Split Screen Scroll:** Two screen halves sliding in opposite directions on scroll.
* **Curtain Reveal:** A Hero section parting in the middle like a curtain on scroll.

### Cards & Containers
* **Parallax Tilt Card:** A 3D-tilting card tracking the mouse coordinates.
* **Spotlight Border Card:** Card borders that illuminate dynamically under the cursor.
* **Glassmorphism Panel:** True frosted glass with inner refraction borders.
* **Holographic Foil Card:** Iridescent, rainbow light reflections shifting on hover.
* **Tinder Swipe Stack:** A physical stack of cards the user can swipe away.
* **Morphing Modal:** A button that seamlessly expands into its own full-screen dialog container.

### Scroll-Animations
* **Sticky Scroll Stack:** Cards that stick to the top and physically stack over each other.
* **Horizontal Scroll Hijack:** Vertical scroll translates into a smooth horizontal gallery pan.
* **Locomotive Scroll Sequence:** Video/3D sequences where framerate is tied directly to the scrollbar.
* **Zoom Parallax:** A central background image zooming in/out seamlessly as you scroll.
* **Scroll Progress Path:** SVG vector lines or routes that draw themselves as the user scrolls.
* **Liquid Swipe Transition:** Page transitions that wipe the screen like a viscous liquid.

### Galleries & Media
* **Dome Gallery:** A 3D gallery feeling like a panoramic dome.
* **Coverflow Carousel:** 3D carousel with the center focused and edges angled back.
* **Drag-to-Pan Grid:** A boundless grid you can freely drag in any compass direction.
* **Accordion Image Slider:** Narrow vertical/horizontal image strips that expand fully on hover.
* **Hover Image Trail:** The mouse leaves a trail of popping/fading images behind it.
* **Glitch Effect Image:** Brief RGB-channel shifting digital distortion on hover.

### Typography & Text
* **Kinetic Marquee:** Endless text bands that reverse direction or speed up on scroll.
* **Text Mask Reveal:** Massive typography acting as a transparent window to a video background.
* **Text Scramble Effect:** Matrix-style character decoding on load or hover.
* **Circular Text Path:** Text curved along a spinning circular path.
* **Gradient Stroke Animation:** Outlined text with a gradient continuously running along the stroke.
* **Kinetic Typography Grid:** A grid of letters dodging or rotating away from the cursor.

### Micro-Interactions & Effects
* **Particle Explosion Button:** CTAs that shatter into particles upon success.
* **Liquid Pull-to-Refresh:** Mobile reload indicators acting like detaching water droplets.
* **Skeleton Shimmer:** Shifting light reflections moving across placeholder boxes.
* **Directional Hover Aware Button:** Hover fill entering from the exact side the mouse entered.
* **Ripple Click Effect:** Visual waves rippling precisely from the click coordinates.
* **Animated SVG Line Drawing:** Vectors that draw their own contours in real-time.
* **Mesh Gradient Background:** Organic, lava-lamp-like animated color blobs.
* **Lens Blur Depth:** Dynamic focus blurring background UI layers to highlight a foreground action.

## 9. THE "MOTION-ENGINE" BENTO PARADIGM
When generating modern SaaS dashboards or feature sections, you MUST utilize the following "Bento 2.0" architecture and motion philosophy. This goes beyond static cards and enforces a "Vercel-core meets Dribbble-clean" aesthetic heavily reliant on perpetual physics.

### A. Core Design Philosophy
* **Aesthetic:** High-end, minimal, and functional.
* **Palette:** Background in `#f9fafb`. Cards are pure white (`#ffffff`) with a 1px border of `border-slate-200/50`.
* **Surfaces:** Use `rounded-[2.5rem]` for all major containers. Apply a "diffusion shadow" (a very light, wide-spreading shadow, e.g., `shadow-[0_20px_40px_-15px_rgba(0,0,0,0.05)]`) to create depth without clutter.
* **Typography:** Strict `Geist`, `Satoshi`, or `Cabinet Grotesk` font stack. Use subtle tracking (`tracking-tight`) for headers.
* **Labels:** Titles and descriptions must be placed **outside and below** the cards to maintain a clean, gallery-style presentation.
* **Pixel-Perfection:** Use generous `p-8` or `p-10` padding inside cards.

### B. The Animation Engine Specs (Perpetual Motion)
All cards must contain **"Perpetual Micro-Interactions."** Use the following Framer Motion principles:
* **Spring Physics:** No linear easing. Use `type: "spring", stiffness: 100, damping: 20` for a premium, weighty feel.
* **Layout Transitions:** Heavily utilize the `layout` and `layoutId` props to ensure smooth re-ordering, resizing, and shared element state transitions.
* **Infinite Loops:** Every card must have an "Active State" that loops infinitely (Pulse, Typewriter, Float, or Carousel) to ensure the dashboard feels "alive".
* **Performance:** Wrap dynamic lists in `<AnimatePresence>` and optimize for 60fps. **PERFORMANCE CRITICAL:** Any perpetual motion or infinite loop MUST be memoized (React.memo) and completely isolated in its own microscopic Client Component. Never trigger re-renders in the parent layout.

### C. The 5-Card Archetypes (Micro-Animation Specs)
Implement these specific micro-animations when constructing Bento grids (e.g., Row 1: 3 cols | Row 2: 2 cols split 70/30):
1. **The Intelligent List:** A vertical stack of items with an infinite auto-sorting loop. Items swap positions using `layoutId`, simulating an AI prioritizing tasks in real-time.
2. **The Command Input:** A search/AI bar with a multi-step Typewriter Effect. It cycles through complex prompts, including a blinking cursor and a "processing" state with a shimmering loading gradient.
3. **The Live Status:** A scheduling interface with "breathing" status indicators. Include a pop-up notification badge that emerges with an "Overshoot" spring effect, stays for 3 seconds, and vanishes.
4. **The Wide Data Stream:** A horizontal "Infinite Carousel" of data cards or metrics. Ensure the loop is seamless (using `x: ["0%", "-100%"]`) with a speed that feels effortless.
5. **The Contextual UI (Focus Mode):** A document view that animates a staggered highlight of a text block, followed by a "Float-in" of a floating action toolbar with micro-icons.

## 10. FINAL PRE-FLIGHT CHECK
Evaluate your code against this matrix before outputting. This is the **last** filter you apply to your logic.
- [ ] Is global state used appropriately to avoid deep prop-drilling rather than arbitrarily?
- [ ] Is mobile layout collapse (`w-full`, `px-4`, `max-w-7xl mx-auto`) guaranteed for high-variance designs?
- [ ] Do full-height sections safely use `min-h-[100dvh]` instead of the bugged `h-screen`?
- [ ] Do `useEffect` animations contain strict cleanup functions?
- [ ] Are empty, loading, and error states provided?
- [ ] Are cards omitted in favor of spacing where possible?
- [ ] Did you strictly isolate CPU-heavy perpetual animations in their own Client Components?
- [ ] Does the output read as Linear/Vercel-tier (Section 0 canon + claude.ai/design taste engine applied), not generic?
