narrative: |
  corpus-insta-dwgvssyjhsr is built on a near-black canvas (rgb(24, 24, 24)).
  The system uses rgb(231, 78, 22) as the high-saturation accent for primary actions.
  Moderately rounded CTAs (12px) — modern SaaS standard, neither sharp nor pill alongside system-ui as the primary typeface.
  Depth comes from borders and surface contrast rather than shadows — a flat, structural elevation model.

## 0. Design DNA

**Density**: moderate  |  **Motion**: still  |  **Weight**: light  |  **Aesthetic**: dark-premium

| Dimension | Value | Signal |
|---|---|---|
| Canvas | dark | `#181818` |
| Type posture | sans-led (system-ui) | display type |
| Color assertion | dual-accent | #e74e16 |
| Whitespace | moderate | section rhythm 48px |
| Interaction | still | 0 keyframes, 0 transitions |
| Radius language | 8px-rounded | from token scale |

**Prism fingerprint**: `dark-canvas · sans-display · dual-accent · 8px-rounded · still-motion`

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(24, 24, 24)` is the page background. Every component composits against this.
> - **Accent**: `rgb(231, 78, 22)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 48px between major bands. Card padding: 24px.
> - **Default radius**: 8px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.
> - **Forbidden**: Do NOT introduce heavy box-shadows — this system relies on borders for separation
>
> **Before generating UI**: import this DESIGN.md, scan §2 (Color Palette) + §4 (Components) + §10 (Agent Guide). Skip §11–12 unless extending.

## 1. Visual Theme & Atmosphere

corpus-insta-dwgvssyjhsr commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is a dark surface (`#181818`) where surfaces are layered through stepped luminance — each elevated level is slightly less dark than the one beneath it, creating depth without color shifts. 

The system font stack (system-ui) trades brand voice for performance and platform familiarity. 

Body text reads in Bright Orange (`#e84810`) — slightly under-bright, preventing eye strain on the dark surface. **Bright Orange** (`#e74e16`) is the single high-saturation color in the system — it earns its presence only on interactive elements, making CTAs and links the unmistakable focal points against the otherwise neutral palette. Shadow is absent by design — depth is conveyed through borders, spacing, and color differentiation rather than light simulation. 


**Key Characteristics:**
- Background: Near-Black (`#181818`)
- Primary text: Bright Orange (`#e84810`)
- Accent: Bright Orange (`#e74e16`)

## 2. Color Palette & Roles

### Background & Surface
- **Near-Black** (`#181818`): Page background (primary)
- **Near-Black** (`#101010`): Surface / elevated background
- **Near-Black** (`#202020`): Surface / elevated background
- **Near-Black** (`#282828`): Surface / elevated background
- **Pure Black** (`#080808`): Surface / elevated background

### Text & Content
- **Bright Orange** (`#e84810`): Primary body text

### Accent & Interactive
- **Bright Orange** (`#e74e16`): Interactive / accent
- **#a93d17** (`#a93d17`): Interactive / accent
- **#c64717** (`#c64717`): Interactive / accent
- **Chocolate** (`#702810`): Interactive / accent
- **Vermillion** (`#d04818`): Interactive / accent

### Border & Divider
- **Charcoal** (`#303030`): Borders / dividers
- **Charcoal** (`#383838`): Borders / dividers

### Full Extracted Palette
**18 colors rendered on the page**. (13 categorized above + 5 additional below.)
Colors are measured at the pixel from a corpus of screenshots (dominant palette + a 2nd HLS "vivid" pass that recovers low-surface brand accents); font sizes are NOT measured (no getComputedStyle). Color **names** are nearest-neighbor labels (no brand CSS variables to read) — treat them as deduced, not declared. Third-party logo colors are filtered out.

- `#5a2e1a` — #5a2e1a
- `#7c341a` — Chocolate
- `#491e12` — Warm Brown
- `#8c642b` — #8c642b
- `#73532b` — #73532b

## 3. Typography Rules

### Font Families

### Typography Hierarchy

| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|

## 4. Component Stylings

### Buttons

**Primary Brand**
- Background: `#e74e16` `{colors.primary}`
- Text: `#ffffff` `{colors.hairline}`
- Padding: 0px
- Radius: 12px
- Font: ? weight ?
- Use: Primary CTA / brand action


## 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
- **1 shape(s)** in this system: `Primary Brand`
- **DO NOT introduce new buttons variants** without justification

## 5. Layout Principles

### Layout Type
**top-nav + content**

### Grid
Single column, centered content

### Max Width
1200px

### Spacing System
Compact spacing — information density prioritized

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 4px |
| sm | 8px |
| md | 12px |
| base | 16px |
| lg | 24px |
| xl | 32px |
| 2xl | 48px |
| 3xl | 64px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 4px | Tiny corners (badges, micro elements) |
| Sm | 8px | Buttons, inputs, small elements |
| Md | 14px | 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 | `12px` |
| Page Body | `0px` |

**Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill.


## 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** | `8px` | Form fields, tight clusters, badge padding |
| **micro** | `4px` | 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.).

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |

**Shadow Philosophy**: Flat design — no shadows used. Borders and spacing define structure.

## 8. Do's and Don'ts

### Do
- Use dark background (`#181818`) as the foundation — this is a dark-mode-native design
- Use Bright Orange (`#e74e16`) as the primary accent — it's the brand's signature interactive color

### Don't
- Don't use light backgrounds — the dark canvas is the native medium
- Don't introduce additional saturated accent colors — the palette is intentionally controlled


## 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(24, 24, 24)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "visual check — no DOM to assert against (source: image-corpus)"
  - id: brand-accent-001
    type: do
    rule: "Reserve `rgb(231, 78, 22)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "visual check — no DOM to assert against (source: image-corpus)"
  - id: brand-depth-001
    type: dont
    rule: "Do NOT introduce drop shadows on cards or sections"
    why: "Containment is achieved via borders, not elevation — adding shadows breaks the depth contract"
    test: "visual check — no DOM to assert against (source: image-corpus)"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | 640px | Single column layout |
| Tablet | 768px | 2-column grids |
| Desktop | 1024px | Full layout |
| Large Desktop | 1280px | Maximum width |

### Collapsing Strategy
- Navigation: horizontal links → hamburger menu on mobile
- Cards: multi-column → stacked vertical on mobile
- Footer: multi-column → stacked single column on mobile

### Touch Targets
- Buttons: 0px padding
- Navigation: adequate spacing between items
- Interactive elements: minimum 44px touch target recommended

## 10. Agent Prompt Guide

### Quick Reference
- Background: Near-Black (`#181818`)
- Primary text: Bright Orange (`#e84810`)
- Accent: Bright Orange (`#e74e16`)
- Border: Translucent Pure White (8%) (`rgba(255, 255, 255, 0.08)`)
- Font: system-ui
- Body: 16px weight 400

### Example Component Prompts
- "Create the primary CTA button: `#e74e16` background, `#ffffff` text, 12px border-radius, 11px 21px padding, 400 weight, system-ui font."
- "Build navigation: sticky on `#181818`. system-ui 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the dark canvas to Near-Black (`#181818`) — every component is composited against this exact base.
2. **Typography**: All type in system-ui. Font weight was not measured from this source — apply the brand's usual weights when cloning.
3. **Accent**: Bright Orange (`#e74e16`) is the sole interactive color. On hover → #a93d17 (`#a93d17`). Use CSS transitions, not opacity/brightness filters.
4. **Spacing**: Spacing was not measured from this source — apply a consistent 4–32px scale (synthesized default) when cloning.
5. **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-canvas: #181818;
  --ca-surface-1: #101010;
  --ca-surface-2: #202020;
  --ca-ink-muted: #e84810;
  --ca-ink-subtle: #9f3713;
  --ca-primary: #e74e16;
  --ca-on-primary: #111111;
  --ca-primary-hover: #a93d17;
  --ca-hairline: #ffffff;
}

/* Spacing & Radius */
:root {
  --ca-space-xxs: 2px;
  --ca-space-xs: 4px;
  --ca-space-sm: 8px;
  --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: 4px;
  --ca-radius-sm: 8px;
  --ca-radius-md: 14px;
  --ca-radius-lg: 20px;
  --ca-radius-xl: 32px;
  --ca-radius-full: 9999px;
}
```

## Coverage: 26% of dimensions extracted

> Coverage measures how much of the design we could read, **not** how pixel-faithful a clone is. For fidelity, see the SSIM/structure score.

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 18 | 25 | 13 named colors |
| Typography | 0 | 20 | 0 roles defined |
| Components | 4 | 20 | 1 specs extracted |

| Responsive Breakpoints | 4 | 5 | 4 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:*

- **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 |
|----------|----------------|-------------------|
| **Photography** | No photographic content detected on this page | Don't add stock imagery; clarity comes from type + color blocks |
| **Motion / Animation** | No @keyframes or transitions detected | Either keep clones strictly static, or apply a single 150ms ease-out on hover/focus universally |
| **Component states** | Hover / focus / active states not captured | Darken background ~10% on hover, add 2px focus ring matching accent token, +50% opacity for disabled |
| **Dark mode** | Dark surface is the canonical medium; no separate light-mode variables detected | The dark canvas IS the design — reproduce it as the default. Do not generate a light-mode variant unless explicitly requested |
| **Form inputs** | No text input fields detected on this page | Use the documented border-radius + accent border on focus; 12-16px padding inside |
| **Design tokens** | Only 0 CSS custom properties (low signal for semantic naming) | Color names are nearest-neighbor approximations; verify against brand guidelines if available |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg measured at the pixel |
| §2 Colors | Low | 0 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | Low | 0 typography roles inferred |
| §4 Components | Low | 1 component variants captured |
| §7 Motion | Low | No motion data |
| §8 Do's/Don'ts | Medium | 4 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 4 breakpoints detected |
| §9b Photography | Low | 0 images, hero not detected |
