# Frontend Design > Design and build production-grade, intentional, premium web interfaces. Enforces strict design systems (spacing, typography, colors, layout, motion), integrates Impeccable craft passes (bolder, quieter, typeset, polish) and Motion taste (Emil Kowalski micro-interactions), and bans the 20 common AI UI slop anti-patterns.

Your goal: interfaces that look **crafted, intentional, and production-grade** — never developer-default or generic AI slop. --- ## The 20 AI Design Slop Sins (BANNED BY DEFAULT) Never use any of these 20 patterns unless the user explicitly requests one as a deliberate creative choice: ``` ┌─────────────────────────────────────────────────────────────────────────────────────────┐ │ THE 20 BANNED AI DESIGN SLOP PATTERNS │ ├─────────────────────────────────────────────────────────────────────────────────────────┤ │ 1. Purple-to-blue gradient backgrounds or hero accents │ │ 2. Gradient hero text (bg-gradient-to-r text-transparent bg-clip-text) │ │ 3. Floating badge or pill directly above headline ("✨ AI-Powered Magic") │ │ 4. Three icon boxes in a row (the cliché feature triad) │ │ 5. Emojis in headings or section titles (🚀, 💡, 🔥) │ │ 6. Colored left-border accent cards (border-l-4 border-indigo-500) │ │ 7. Glassmorphism cards (heavy backdrop-blur + semi-transparent white border) │ │ 8. Untouched shadcn/ui components dropped in as-is without tailoring │ │ 9. Lucide icon overload (icons in front of every single word or bullet) │ │ 10. Default Inter font everywhere without typographic hierarchy │ │ 11. Cliché Space Grotesk + Instrumental Serif combination everywhere │ │ 12. Serif italics for accent words (e.g., "for *innovative* teams") │ │ 13. Em dashes (—) or double hyphens (--) littered across marketing copy │ │ 14. Generic corporate buzzwords ("seamless", "elevate", "supercharge", "unleash") │ │ 15. Heavy section opacity fade-in on scroll │ │ 16. Cursor-following glow, lines, or trailing particle dots │ │ 17. Buttons that fade opacity on hover (instead of crisp, tactile state shifts) │ │ 18. Low-contrast dark mode (unreadable dark grays violating WCAG AA) │ │ 19. Inconsistent, arbitrary spacing (mixing 7px, 13px, 22px instead of 4px/8px scale) │ │ 20. Grain or noise texture overlays applied indiscriminately │ └─────────────────────────────────────────────────────────────────────────────────────────┘ ``` --- ## 1. The Design System Core Standards ### A. Spacing — Strict 4px/8px Scale - **Scale**: `4px (1)`, `8px (2)`, `12px (3)`, `16px (4)`, `24px (6)`, `32px (8)`, `48px (12)`, `64px (16)`, `96px (24)`. - Never use random values (`13px`, `7px`, `22px`). - **Proximity Rule**: - Related items: small gap (8–12px). - Unrelated groups: large gap (32–64px). - Web section padding: 64–96px vertical. Let the content breathe. ### B. Typography — Restraint & Contrast - Maximum 2 font families (one clean sans for UI/body, optional display font). - Maximum 3–4 sizes in a view with high weight/size contrast: - Display / H1: Bold / tight tracking (`tracking-tight`). - Body: 16px (`text-base`), line-height 1.5–1.6, regular weight. - Muted / Small: 14px (`text-sm`), muted color token. - Tabular figures for data/numbers: `font-variant-numeric: tabular-nums`. ### C. Color Tokens & Neutrals - **90% Neutrals**: High-quality gray ramp (Slate, Zinc, or Stone) for backgrounds, borders, and typography. - **1 Brand Accent**: Used sparingly on primary interactive triggers (buttons, active states). - **Semantic Colors**: Green (success), Red (danger), Amber (warning), Blue (info). - **Dark Mode**: High contrast. True background `#09090b` or `#0a0a0a`, distinct elevated surface `#18181b`, border `#27272a`. Minimum text contrast 4.5:1 (WCAG AA). ### D. Depth & Elevation - Subtle 1px borders (`border-zinc-200` or `border-zinc-800`). - Directional, multi-layered shadows instead of flat glows: ```css box-shadow: 0 1px 2px rgba(0, 0, 0, 0.05), 0 4px 12px rgba(0, 0, 0, 0.08); ``` --- ## 2. Impeccable Craft Passes (`impeccable/`) When designing or refining interfaces, apply these specialized craft passes: - **Bolder (`impeccable/reference/bolder.md`)**: - Double down on scale contrast (giant hero typography vs crisp microcopy). - Commit to extreme alignment and solid, confident surface treatments. - **Quieter (`impeccable/reference/quieter.md`)**: - Remove unnecessary decorative borders and noisy background badges. - Soften high-contrast secondary text to muted neutrals. Let whitespace do the work. - **Typeset (`impeccable/reference/typeset.md`)**: - Enforce strict optical alignment, proper line-lengths (50–75 chars max), and negative tracking on large headings. - **Polish (`impeccable/reference/polish.md`)**: - Refine interactive active/hover states, focus rings, border-radius derivations (inner radius = outer radius - padding). - **Delight (`impeccable/reference/delight.md`)**: - Thoughtful details: keyboard shortcuts indicators (`⌘K`), tactile button press shifts (`active:scale-[0.98]`). --- ## 3. Motion & Micro-Interactions (`motion/`) Based on Emil Kowalski's motion standards: - **Physicality**: - Animations must feel weighted and physical, not linear or floaty. - Durations: 150ms–250ms for micro-interactions (tooltips, buttons); 300ms–400ms for drawers, modals, and tab switches. - **No Scroll-Fade Slop**: - Never apply blanket opacity fade-ins as sections enter the viewport. - Use layout-driven transitions (e.g. gliding indicator bar under active tab with GSAP `power2.out`). - **Snappy Hover & Active**: - Crisp background or border color shifts, never slow opacity fades. - Subtle spring-like feel: `active:scale-[0.98] transition-transform duration-100`. --- ## 4. Aesthetic Presets (`taste/`) For specific visual directions, draw upon `taste/` subskills: - **Minimalist (`taste/minimalist-skill`)**: Ultra-clean, neutral-dominated, high whitespace, typography-first. - **Brutalist (`taste/brutalist-skill`)**: Monospaced accents, high-contrast borders, bold geometry, raw utility. - **Soft / Refined (`taste/soft-skill`)**: Subtle pill radii, warm neutrals, delicate micro-borders.
