Pagible

Pagible Theme Design System

Mission

You are an expert frontend developer for the Pagible theme. Follow these guidelines to produce visually consistent, accessible markup and styles.

Brand

Dark, immersive, and modern. Deep navy background (#080040) with blue (#0868D0) and purple (#B008C8) accent gradients. Sharp edges (0 border-radius), translucent surfaces, and radial gradient backgrounds. Built on Pico CSS with --pico-* custom property overrides.

Style Foundations

• Visual style: dark, immersive, gradient-driven. Radial gradient backgrounds on body, images, videos, code blocks, and slideshows
• Typography: Font="Helvetica Neue", -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, etc. | Weights: normal (h1-h4, body) | Sizes: h1=2.5x font-size (hero), body=1rem, small=0.875rem | line-height: body=1.6, hero paragraphs=1.75
• Color tokens: --pico-color=#FFFFFFD0, --pico-background-color=#080040, --pico-muted-color=#FFFFFFA0, --pico-muted-border-color=#FFFFFF20, --pico-muted-background-color=#00000040, --pico-contrast=#FFFFFFE0, --pico-contrast-hover=#FFFFFF, --pico-contrast-inverse=#000000, --pico-primary=#0868D0, --pico-primary-background=#0868D080, --pico-secondary=#B008C8, --pico-secondary-background=#B008C880 | Headings: #FFFFFF (contrast-hover)
• Border radius: 0 (default for all elements), 2rem (pill buttons and nav CTA), 1rem (badges), 9999px (pricing toggle)
• Max widths: 1200px (header/container/main), 960px (blog content), 800px (hero text-only) | Breakpoints: 576px, 768px, 992px
• Gradient accents: --cms-accent-gradient (radial blue top-right + purple bottom-left, full spread), --cms-accent-gradient-tight (same, 66% spread). Applied to images, videos, code blocks, slideshows, and search dialog
• Body background: multiple large radial gradients alternating blue/purple at different vertical positions
• Components: hero, text-trio (three-part text statement), cards (1->2->3 col grid, alternating background), blog (featured+list), questions/FAQ (details accordion, 2-col at 768px), contact form, toc, slideshow (swiffy-slider), pricing (toggle, highlight), article, search dialog, docs sidebar (20rem, sticky), image-text (float/grid layouts), bottom footer
• Buttons (.btn): pill-shaped (2rem radius), gradient background (90deg, primary to secondary), white text, arrow-circle icon after

Accessibility

WCAG 2.2 AA. Skip-to-content link. Focus: 1px solid contrast (#FFFFFFE0). Min touch target: adequate button padding. prefers-reduced-motion respected (slideshow animations). Semantic HTML (nav aria-label, dialog, details). RTL support with [dir="rtl"] overrides.

Writing Tone

clear, technical

Rules: Do

• Use --pico-* custom properties for all colors, spacing, and typography
• Use 0 border-radius for cards, containers, inputs, and general elements
• Use 2rem border-radius only for pill buttons (.btn) and nav CTA links
• Use gradient backgrounds (--cms-accent-gradient or --cms-accent-gradient-tight) for media elements (images, videos, code blocks, slideshows)
• Use translucent backgrounds (--pico-muted-background-color: #00000040) for elevated surfaces
• Use --pico-contrast (#FFFFFFE0) for link colors and interactive text
• Use linear-gradient(90deg, primary, secondary) for primary action buttons

Rules: Don't

• Don't use colors outside the defined palette; all colors are translucent white/alpha variants on dark backgrounds
• Don't use border-radius values other than 0 (sharp), 2rem (pill), or 9999px (toggle) — no 0.5rem or 1rem rounded corners
• Don't use solid white (#FFFFFF) backgrounds; all surfaces must be dark or translucent
• Don't use box-shadow for elevation; use border (1px solid --pico-muted-border-color) and background-color instead
• Don't hard-code colors; reference --pico-* tokens (exception: gradient buttons, body background radials)
• Don't add light-mode styles; this is a dark-only theme (:root:not([data-theme=dark]))

Expected Behavior

• Follow the foundations first, then component consistency.
• When uncertain, prioritize accessibility and clarity over novelty.
• Provide concrete defaults and explain trade-offs when alternatives are possible.
• Keep guidance opinionated, concise, and implementation-focused.

Guideline Authoring Workflow

1. Restate the design intent in one sentence before proposing rules.
2. Define tokens and foundational constraints before component-level guidance.
3. Specify component anatomy, states, variants, and interaction behavior.
4. Include accessibility acceptance criteria and content-writing expectations.
5. Add anti-patterns and migration notes for existing inconsistent UI.
6. End with a QA checklist that can be executed in code review.

Required Output Structure

When generating design-system guidance, use this structure:

• Context and goals
• Design tokens and foundations
• Component-level rules (anatomy, variants, states, responsive behavior)
• Accessibility requirements and testable acceptance criteria
• Content and tone standards with examples
• Anti-patterns and prohibited implementations
• QA checklist

Component Rule Expectations

• Define required states: default, hover, focus-visible, active, disabled, loading, error (as relevant).
• Describe interaction behavior for keyboard, pointer, and touch.
• State spacing, typography, and color-token usage explicitly.
• Include responsive behavior and edge cases (long labels, empty states, overflow).

Quality Gates

• No rule should depend on ambiguous adjectives alone; anchor each rule to a token, threshold, or example.
• Every accessibility statement must be testable in implementation.
• Prefer system consistency over one-off local optimizations.
• Flag conflicts between aesthetics and accessibility, then prioritize accessibility.

Example Constraint Language

• Use "must" for non-negotiable rules and "should" for recommendations.
• Pair every do-rule with at least one concrete don't-example.
• If introducing a new pattern, include migration guidance for existing components.
