--- version: alpha name: hono.dev description: "Light product system built on #ffffff with #f6f6f7 as the primary CTA accent. Type anchored in -apple-system at 56px / weight 700. Extracted automatically from https://hono.dev/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)." narrative: | hono.dev is built on a pure-white canvas (rgb(255, 255, 255)). The system uses rgb(246, 246, 247) as a near-neutral accent (low saturation). Moderately rounded CTAs (8px) — modern SaaS standard, neither sharp nor pill alongside -apple-system as the primary typeface. A restrained elevation system (2 distinct shadows) — shadows reserved for the few elements that must lift off the page. Interactions are smoothed by transitions across many elements, with little or no keyframe animation. colors: background: "#ffffff" surface-1: "#f6f6f7" surface-2: "#ebebef" ink: "#1f2328" ink-subtle: "#808080" primary: "#f6f6f7" on-primary: "#111111" primary-hover: "#e4e4e9" hairline: "#454545" primary-focus: "#101010" semantic-error: "rgba(244, 63, 94, .14)" semantic-success: "#18794e" semantic-warning: "#915930" semantic-info: "#bff8d7" typography: display-xl: fontFamily: "Inter, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 400 lineHeight: 1.5 letterSpacing: 0 display-md: fontFamily: "apple color emoji, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 16px fontWeight: 700 lineHeight: 1.5 letterSpacing: 0 body: fontFamily: "apple color emoji, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 12px fontWeight: 700 lineHeight: 2 letterSpacing: 0 body-sm: fontFamily: "apple color emoji, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 14px fontWeight: 500 lineHeight: 4.57 letterSpacing: 0 caption: fontFamily: "apple color emoji, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 24px fontWeight: 500 lineHeight: 1.5 letterSpacing: 0 button: fontFamily: "apple color emoji, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 13.3333px fontWeight: 500 lineHeight: 1.8 letterSpacing: 0 rounded: none: 0px xs: 6px sm: 8px md: 12px lg: 20px xl: 32px pill: 9999px spacing: xxs: 2px xs: 8px sm: 10px md: 12px lg: 24px xl: 32px xxl: 64px components: button-light--invert: backgroundColor: "{colors.primary}" textColor: "{colors.hairline}" typography: "{typography.button}" rounded: "{rounded.sm}" padding: 0px 10px 0px 12px button-pill: backgroundColor: "#8e96aa" textColor: "{colors.ink}" typography: "{typography.button}" rounded: "{rounded.md}" button-pill-2: backgroundColor: "{colors.background}" textColor: "#e36002" typography: "{typography.body}" rounded: "{rounded.sm}" padding: 8px 16px card-standard-card: backgroundColor: "transparent" typography: "{typography.display-xl}" rounded: "{rounded.none}" padding: 24px extracted_at: "2026-06-11T06:10:08.253Z" completeness: 66 scoreVersion: "v2" --- # Design System — hono.dev > Extracted automatically by Prism from https://hono.dev > Date: 2026-06-11 > Viewport: Desktop 1440x900 + Mobile 390x844 > Values are extracted, not hand-written: rendered styles via getComputedStyle() + colors declared in CSS custom properties (token-only values are marked `(token)` and may not be painted). ## 0.

Skip §11–12 unless extending. ## 1. Visual Theme & Atmosphere hono.dev uses a pure-white canvas (`#ffffff`), letting typography, color and imagery carry the visual weight. The system font stack (-apple-system) trades brand voice for performance and platform familiarity. Body text reads in Near-Black (`#1f2328`) — softened from pure black, a small but deliberate detail that lowers reading friction. **Off-White** (`#f6f6f7`) provides interactive distinction without visual aggression. Elevation comes from a small, deliberate set of shadows (2 distinct), each a multi-layer stack — several blurred layers at varying offsets — used sparingly rather than across the whole UI. **Key Characteristics:** - Background: Pure White (`#ffffff`) - Primary typeface: Inter - Primary text: Near-Black (`#1f2328`) - Accent: Off-White (`#f6f6f7`) - Shadow system: 2 distinct elevation levels - Custom fonts loaded: Inter, Punctuation SC ## 2. Color Palette & Roles ### Background & Surface - **Pure White** (`#ffffff`): Page background (primary) - **Off-White** (`#f6f6f7`): Surface / elevated background - **Whitesmoke** (`#ebebef`): Surface / elevated background ### Text & Content - **Near-Black** (`#1f2328`): Primary body text - **Pure Black** (`#000000`): Secondary text - **Translucent Dark Gray (12%)** (`rgba(60, 60, 67, 0.12)`): Secondary text ### Accent & Interactive - **Bright Orange** (`#e36002`): Interactive / accent - **Translucent Cool Gray (14%)** (`rgba(142, 150, 170, 0.14)`): Interactive / accent - **#ff9c24** (`#ff9c24`): Interactive / accent ### Full Extracted Palette **11 colors rendered on the page** + **57** more declared in design tokens (CSS custom properties — not necessarily painted). (9 categorized above + 59 additional below.) Rendered values are read via `getComputedStyle()`; token values come from CSS variable declarations.

Component Behaviors (State Matrix) ### Interaction State Narrative - **Button**: - **hover:** bg #f6f6f7 → #ffffff, text #454545 → #1f2328 - **focus:** bg #f6f6f7 → transparent, text #454545 → #1f2328, border changes *State transitions extracted via Playwright simulation — exact values in the YAML matrix below.* ```yaml component-behaviors: button: default: bg: "rgb(246, 246, 247)" fg: "rgb(69, 69, 69)" border: "1px solid rgba(0, 0, 0, 0)" hover: bg: "rgb(255, 255, 255)" fg: "rgb(31, 35, 40)" focus: bg: "rgba(0, 0, 0, 0)" fg: "rgb(31, 35, 40)" border: "1px solid rgba(227, 96, 2, 0.05)" link: default: bg: "rgb(255, 255, 255)" fg: "rgb(227, 96, 2)" shadow: "rgba(0, 0, 0, 0.1) 0px 12px 32px 0px, rgba(0, 0, 0, 0.08) 0p" card: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(31, 35, 40)" navLink: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(31, 35, 40)" badge: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(69, 69, 69)" ``` **Agent usage**: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand. ## 4c. Component Vocabulary (Closed System) *This brand uses ONLY the following component vocabulary. Introducing new variants without justification breaks the system's tonal coherence.* ### Buttons - **2 shape(s)** in this system: `Light / Invert`, `Pill` - **DO NOT introduce new buttons variants** without justification ### Cards & Containers - **1 shape(s)** in this system: `Standard Card` - **DO NOT introduce new cards & containers variants** without justification ## 5. Layout Principles ### Layout Type **top-nav + content** ### Grid Single column, centered content ### Max Width 1440px ### Spacing System Compact spacing — information density prioritized | Token | Value | |-------|-------| | xxs | 2px | | xs | 8px | | sm | 10px | | md | 12px | | base | 16px | | lg | 24px | | xl | 32px | | 2xl | 48px | | 3xl | 64px | ### Border Radius Scale | Name | Value | Use | |------|-------|-----| | None | 0px | No rounding | | Xs | 6px | Tiny corners (badges, micro elements) | | Sm | 8px | Buttons, inputs, small elements | | Md | 12px | Cards, containers | | Lg | 20px | Large rounded elements, pill segments | | Xl | 32px | Category strips, featured containers | | Full | 9999px | Pills, avatars, circular elements | ### Shape Language | Component | Border Radius | |-----------|---------------| | Buttons | `8px` | | Cards & Containers | `0px` | | Page Body | `0px` | | Navigation | `0px` | **Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill. **Full Radius Spectrum**: 0px, 4px, 6px, 8px, 11px, 12px, 20px (from `allBorderRadii` scan) ## 5b. Spacing Rhythm Names *Named spacing tokens with explicit use cases. Use these names in YOUR code instead of raw pixels for consistency.* | Name | Value | Use case | |------|-------|----------| | **hero** | `64px` | Top/bottom of full-bleed hero sections | | **section** | `32px` | Between major bands (color change, content shift) | | **subsection** | `24px` | Within a section, between content groups | | **card** | `12px` | Card padding, list-item spacing | | **compact** | `10px` | Form fields, tight clusters, badge padding | | **micro** | `8px` | Icon-text gap, tag inner padding | **Agent rule**: NEVER hardcode raw pixel values for spacing in generated UI. Always reference these named tokens (`spacing-rhythm.section`, etc.). ## 5c. Widget & Structure Library Structural patterns extracted from the page DOM — these are the **blueprints** an agent should follow to reproduce the page architecture (not just CSS values). **4/8 structural patterns detected.** ### Hero Pattern - **Composition:** left-aligned — - **Viewport coverage:** 348px tall (not full-viewport) - **Heading:** "HonoWeb application framework" — 16px left-aligned - **Subheading:** "Fast, lightweight, built on Web Standards. Support for any JavaScript runtime." - **CTAs:** 2 (primary: "Get Started") - **Clone instruction:** Reproduce the **left-aligned** layout. Use the heading font-size token at the documented size. Pair the centered text with the hero’s decorative visual (gradient / SVG / hero image — see §9b), not bare text. ### Navigation Pattern - **Position:** static (scrolls with page) - **Layout:** unknown — Layout not classified - **Height:** 64px - **Logo:** ✗ absent - **Nav links:** 3 primary items - **CTAs in nav:** 0 (no buttons — links only) - **Clone instruction:** Build a static unknown navigation. Link-only — no button styling needed. ### Card Grid Pattern - **Card count:** 4 cards detected - **Columns (desktop):** 5-up grid - **Card dimensions:** 292×262px (aspect 1.11:1) - **Gap:** 0px between cards - **Content:** ✗ no image - **Clone instruction:** Build a 5-column grid (desktop) with cards at ~1.11:1 aspect ratio. Text/icon-only cards (no photography). ### Footer Pattern - **Columns:** 1 - **Links:** 0 total - **Height:** 113px - **Includes:** ✗ no newsletter | ✗ no social | ✓ copyright - **Clone instruction:** Build a 1-column footer with ~0 links per column, and a copyright line. ## 6. Depth & Elevation | Level | Treatment | Use | |-------|-----------|-----| | Flat (Level 0) | No shadow | Page background, content blocks | | Layered (Level 1) |
`rgba(0, 0, 0, 0.1) 0px 12px 32px 0px`,
`rgba(0, 0, 0, 0.08) 0px 2px 6px 0px` | Cards, elevated surfaces | | Layered (Level 2) |
`rgba(0, 0, 0, 0.04) 0px 1px 2px 0px`,
`rgba(0, 0, 0, 0.06) 0px 1px 2px 0px` | Cards, elevated surfaces | **Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation. ## 7. Motion & Interaction ### Duration Scale | Value | Tier | Typical Use | |-------|------|-------------| | `250ms` | Normal | Panel open/close, navigation | | `500ms` | Slow | Hero animations, page transitions | ### Copy-Paste Transition Snippets **Background** ```css transition: background-color 0.5s; ``` **Background** ```css transition: background-color 0.25s; ``` **Opacity** ```css transition: opacity 0.25s; ``` **Border** ```css transition: border-color 0.25s; ``` ### Keyframe Animation Catalog | Animation Name | Type | Animated Props | Use Hint | |----------------|------|----------------|----------| | `fade-in` | Fade | opacity | Element entrance | ### Motion Fingerprint - **Speed Character**: Deliberate & Calm (median duration: `500ms`) - **Dominant Easing**: standard CSS easings - **Animation Library**: 1 unique animation (1 total including variants) > This design moves with deliberate & calm timing using standard CSS easings, creating a UI that feels calm and controlled. ## 8. Do's and Don'ts ### Do - Use Near-Black (`#1f2328`) for text — not pure black, it's warmer and more readable - Use the extracted shadow patterns for elevation — they are tuned to match the brand palette - Use Off-White (`#f6f6f7`) as the primary accent — it's the brand's signature interactive color - Use 8px border-radius on buttons — the standard corner rounding for interactive elements - Apply 24px padding inside cards — matches the design system's content breathing room - Maintain nav height at 64px — consistent vertical space for the navigation bar - Transition button background to Pure White (`#ffffff`) on hover — this is the extracted interactive state - Include exactly 2 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose - Use a 5-column grid on desktop — density matters for this content type ### Don't - Don't use pure black (`#000000`) for text — the near-black adds warmth - Don't invent new shadow values — use only the extracted shadow levels - Don't introduce additional saturated accent colors — the palette is intentionally controlled - Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence - Don't use opacity or brightness filter for button hover — the design uses an explicit background color change - Don't make the nav sticky — this design lets it scroll away to maximize content focus - Don't put a CTA button in the nav — this design uses links only at the top - Don't over-build the footer — this design keeps it minimal (1 cols, 0 links) ## 7b. Enforceable Brand Rules *Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.* ```yaml rules: - id: brand-canvas-001 type: do rule: "Always use the page background `rgb(255, 255, 255)` as the base canvas" why: "Every component is designed to composit against this exact tone" test: "document.body.style.backgroundColor === 'rgb(255, 255, 255)'" - id: brand-accent-001 type: do rule: "Reserve `rgb(246, 246, 247)` for primary CTAs and brand-mark signals only" why: "Single chromatic assertion device — overuse dilutes meaning" test: "querySelectorAll('[style*=\"rgb(246, 246, 247)\"]').length <= 3 per fold" ``` ## 9. Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |------|-------|-------------| | Mobile | 375px | Single column, compact spacing | | Mobile Large | 639px | Expanded mobile layout | | Mobile Large | 767px | Expanded mobile layout | | Tablet | 960px | Multi-column grids begin | | Desktop | 1280px | Full feature layout | | Large Desktop | 1440px | Maximum content width | ### Token Diff — Desktop vs Mobile | Element | Property | Desktop | Mobile | |---------|----------|---------|--------| | nav | display | `flex` | `none` | | nav | height | `64px` | `auto` | | button | padding | `0px 10px 0px 12px` | `0px` | | button | width | `145.891px` | `40px` | | card | width | `274px` | `340px` | ### Collapsing Strategy - Navigation: flex → none on mobile - Cards: multi-column → stacked vertical on mobile - Footer: multi-column → stacked single column on mobile ### Touch Targets - Buttons: 0px 10px 0px 12px padding - Navigation: adequate spacing between items - Interactive elements: minimum 44px touch target recommended ### Collapsing Narrative How the structural patterns adapt from desktop to mobile (extracted from both viewport extractions): - **Hero collapses left-aligned → centered** — composition shifts (verify on actual mobile render). - **Card grid: 5-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile. ## 7c. Visual Effects & Dynamic Behavior *The live/dynamic layer beyond static CSS — reproduce these, not flat substitutes. This is often what separates a faithful clone from a wireframe.* - **Clip-path shapes** — 2 non-rectangular cut(s). > **Motion fingerprint**: non-rectangular shapes (2) ## 9b. Visual Tone & Photography **Tone:** Mixed photography + illustration A balanced mix of photographic content and vector graphics. Photos likely carry product/lifestyle context while SVG handles icons, logos, and decorative accents. **Canonical Brand Image (OG):** - https://hono.dev/images/hono-title.png *This is the image shown when the site is shared on social media — represents the brand visual essence.* **Hero Image (above-fold dominant visual):** - Aspect: 1.76:1 (landscape (16:9-ish)) - Rendered size: 564×320px - Alt text: "An example of code for Hono. import { Hono } from 'hono' const app = new Hono() app.get('/', (c) => c.text('Hello Hono!'" - *Use this aspect ratio + composition for your clone's hero — mimicking the proportion preserves the visual hierarchy.* **Aspect Ratio Distribution:** - Landscape (1.15–2.3): 1 (100%) - Portrait (<0.87): 0 (0%) - Square (0.87–1.15): 0 (0%) **Media Format Mix:** - WebP: 1 (optimized photo/illustration hybrid) **Average rendered image size:** 564×320px **Above-fold image count:** 1 / 1 **Imagery Guidance for clones:** - Mix photography and illustration intentionally: photos for product/context, vectors for icons + decorative accents. - Respect the format split — replacing JPGs with illustrations (or vice versa) will shift the brand tone. ## 10. Agent Prompt Guide ### Quick Reference - Background: Pure White (`#ffffff`) - Primary text: Near-Black (`#1f2328`) - Accent: Off-White (`#f6f6f7`) - Border: Charcoal (`#454545`) - Font: apple color emoji - Body: 16px weight 400 ### Example Component Prompts - "Create a hero section on Pure White background (#ffffff). Headline at 16px apple color emoji weight 400, line-height 1.5, color #1f2328." - "Create the primary CTA button: `#f6f6f7` background, `#454545` text, 8px border-radius, 0px 10px 0px 12px padding, 500 weight, apple color emoji font." - "Design a card on `transparent` background. Border: none. Radius: 0px. Shadow: none. Padding: 24px." - "Build navigation: static on `#ffffff`. apple color emoji 16px weight 400 for links." ### Iteration Guide 1. **Canvas**: Set the light canvas to Pure White (`#ffffff`) — every component is composited against this exact base. 2. **Typography**: All type in apple color emoji, weight range 400–700. Never exceed 700 — heavier weights break the brand's tonal restraint. 3. **Accent**: Off-White (`#f6f6f7`) is the sole interactive color. On hover → Bright Orange (`#e36002`). Use CSS transitions, not opacity/brightness filters. 4. **Shape**: CTAs at `8px`, cards at `0px`. Apply border-radius from the extracted scale only — don't invent intermediate values. 5. **Spacing**: Use the `--ca-space-*` token scale (8px–32px). All padding, margin, and gap values are multiples from this scale — no magic numbers. 6. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent. ## 11. CSS Design Tokens Raw Export *Copy-paste ready `:root {}` block — all values extracted directly from the live site.* ```css /* Colors */ :root { --ca-background: #ffffff; --ca-primary: #f6f6f7; --ca-surface-2: #ebebef; --ca-ink: #1f2328; --ca-ink-subtle: #808080; --ca-on-primary: #111111; --ca-primary-hover: #e4e4e9; --ca-hairline: #454545; --ca-primary-focus: #101010; --ca-semantic-error: #f43f5e; --ca-semantic-success: #18794e; --ca-semantic-warning: #915930; --ca-semantic-info: #bff8d7; } /* Typography */ :root { --ca-font-primary: "apple color emoji", system-ui, sans-serif; --ca-text-display: 16px; --ca-text-body: 12px; --ca-text-small: 14px; --ca-text-caption: 24px; --ca-text-button: 13.3333px; } /* Spacing & Radius */ :root { --ca-space-xxs: 2px; --ca-space-xs: 8px; --ca-space-sm: 10px; --ca-space-md: 12px; --ca-space-base: 16px; --ca-space-lg: 24px; --ca-space-xl: 32px; --ca-space-2xl: 48px; --ca-space-3xl: 64px; --ca-radius-none: 0px; --ca-radius-xs: 6px; --ca-radius-sm: 8px; --ca-radius-md: 12px; --ca-radius-lg: 20px; --ca-radius-xl: 32px; --ca-radius-full: 9999px; } ``` ## 13. Page Structure Skeleton *The actual layout the source site uses. Reproduce these sections in order to match the site structure.* ```yaml page-skeleton: - section: content-section tag: div height: 1043px width: full-bleed layout: block children: 1 - section: content-section tag: div classes: ["Layout"] height: 1043px width: full-bleed layout: flex-column justify=normal children: 5 vertical-padding: ~48px - section: unknown tag: div classes: ["image-container"] height: 348px width: 560px layout: flex-row justify=center children: 2 - section: unknown tag: div classes: ["container"] height: 348px width: 1152px layout: flex-row justify=normal children: 2 - section: content-section tag: div classes: ["container"] height: 262px width: 1152px layout: block children: 1 - section: footer tag: footer classes: ["VPFooter"] height: 113px width: full-bleed layout: block children: 1 bg: "rgb(255, 255, 255)" vertical-padding: ~32px padding: "32px" ``` **Agent rule**: rebuild sections in this order (sorted by vertical position). Match the layout primitive (grid N-col / flex direction / block). ## 14. Copy Library (Real Content from Source) *Actual text content extracted from the live page. Use these strings verbatim when reproducing the site — they carry the brand voice.* ```yaml copy: section-headings: - "Ultrafast & Lightweight" ctas: - "Search K" navigation: - "Hono" - "Docs" - "Examples" - "Discussions" ``` **Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording. ## 15. Asset Inventory (Image Roles & Ratios) *Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.* ```yaml assets: icon: count: 1 avg-ratio: 0.79 common-aspect: "~9:16 portrait" ``` **Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`. ## 16. Component HTML Templates *Suggested HTML markup for reproducing the key components — based on what was detected in the source DOM.* ### Button (primary action) ```html ``` _Source pattern detected: padding `0px 10px 0px 12px` · radius `8px` · weight `500`_ ### Generic Card ```html
``` _Source pattern detected: padding `24px` · radius `0px` · shadow `none`_ **Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling. ## 17. Content Architecture & Resources (Links by Purpose) *The page's links classified by purpose — the information architecture to reproduce. Categories, featured images, devices and projects are extracted from the rendered DOM, not guessed.* **By purpose:** **nav** 3 · **cta** 1 · **docs** 1 · **social** 5 · **other** 1 **Primary actions (conversion path):** - Primary call-to-action — "Get Started" (the conversion path) → `https://hono.dev/docs/` **Signals:** 1/11 links carry a featured image · device mockups detected: tablet ×1 · dominant link roles: social-link (5), navigation (3), inline-link (2). --- ## Extraction Completeness: 66/100 (C) | Category | Score | Max | Detail | |----------|-------|-----|--------| | Colors & Palette | 13 | 25 | 9 named colors | | Typography | 20 | 20 | 9 roles defined | | Components | 8 | 20 | 2 specs extracted | | Motion & Interaction | 10 | 15 | Keyframes | | CSS Custom Properties | 10 | 10 | 311 vars | | Responsive Breakpoints | 5 | 5 | 6 breakpoints | | Variable Fonts | 0 | 5 | None detected | ## 12. Known Gaps & Confidence Explicit list of what this extraction could NOT capture. Agents should not invent values for these — either skip the feature or use the documented baseline + heuristic fallback. *Auto-detected extraction limitations — understand before building:* - **Licensed web fonts (Inter)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics). - **Sparse component extraction** — fewer than 5 component types detected. Highly dynamic sections (modals, datepickers, carousels) require interaction to render and are not captured in a static pass. | Category | What's missing | Fallback strategy | |----------|----------------|-------------------| | **Form inputs** | No text input fields detected on this page | Use the documented border-radius + accent border on focus; 12-16px padding inside | ### Per-section confidence | Section | Confidence | Reason | |---------|------------|--------| | §1 Visual Theme | High | Body bg extracted via getComputedStyle() | | §2 Colors | High | 311 CSS vars (semantic naming requires ≥20 for high) | | §3 Typography | High | 9 typography roles inferred | | §4 Components | Low | 2 component variants captured | | §7 Motion | High | Keyframes + transitions | | §8 Do's/Don'ts | High | 17 rules generated; design-decisions.json has evidence per rule | | §9 Responsive | High | 6 breakpoints detected | | §9b Photography | High | 1 images, hero present | ## 11.1 CSS Implementation Guide (CSS Interception Engine v2.15+) *Ready-to-use CSS from Prism's CSS Interception Engine — intercepted directly from the site's CSS files (bypasses CORS).
