## Design Specifications at a Glance

### Color System

**Primary Colors** (HSL Format):

- Background: `36 8% 88%` (light warm gray)
- Foreground: `0 0% 13%` (near black)
- Primary: `216 55% 25%` (deep blue)
- Secondary: `219 14% 28%` (slate blue)
- Accent: `105 22% 25%` (teal green)

**Dark Mode:** Automatic via CSS variables (no Tailwind dark: prefixes needed)

**Contrast Ratios:** All WCAG AAA (4.5:1 body, 3:1 large text)

### Typography Scale

| Level   | Size  | Weight | Use Case       |
| ------- | ----- | ------ | -------------- |
| Body    | 16px  | 400    | Main text      |
| Heading | 30px  | 700    | Section titles |
| Display | 36px+ | 700    | Page titles    |

**Line Heights:** 1.5 body, 1.3 headings, 1.6 large

### Spacing System

**Base Unit:** 4px grid
**Scale:** 4, 8, 12, 16, 20, 24, 32, 40, 48, 64, 96, 128px

**Usage:**

- Component padding: `p-4`, `p-6`, `p-8`
- Section padding: `py-12` mobile → `py-20` desktop
- Gap between items: `gap-4` (16px)

### Breakpoints

```
Mobile:  default (320px+)
Tablet:  md: 768px+
Desktop: lg: 1024px+
XL:      xl: 1280px+
```

### Component Sizes

| Component   | Height | Padding     | Min Width |
| ----------- | ------ | ----------- | --------- |
| Button (sm) | 32px   | px-3 py-1.5 | 64px      |
| Button (md) | 40px   | px-4 py-2   | 80px      |
| Button (lg) | 48px   | px-6 py-3   | 96px      |
| Input       | 40px   | px-4 py-2.5 | 200px     |
| Card        | auto   | p-6         | 256px     |

### Dark Mode

**Implementation:** CSS variables + `.dark` class on `<html>`
**Automatic:** All semantic colors (`bg-primary`, `text-foreground`) auto-switch
**No Manual Prefixes Needed:** Dark mode works without `dark:` utilities for semantic colors

## 5-Section Page Pattern

Every demo page follows this structure:

```
┌─────────────────────────────┐
│ 1. HERO                     │  Headline + subheading + CTAs
│    (py-20 → py-32)          │  Background gradient blur effects
├─────────────────────────────┤
│ 2. PLAYGROUND               │  Form + live JSON data
│    (py-16 → py-20)          │  2-column layout on desktop
│    (bg-card)                │  Real-time stat updates
├─────────────────────────────┤
│ 3. CODE EXAMPLES            │  Copy-paste ready snippets
│    (py-16 → py-20)          │  Syntax highlighted
│    (dark background)        │  Key points + related docs
├─────────────────────────────┤
│ 4. RELATIONSHIP EXPLORER    │  Interactive graph visualization
│    (py-16 → py-20)          │  2/3 graph + 1/3 properties panel
│    (bg-card border-y)       │  Click nodes to explore
├─────────────────────────────┤
│ 5. CTA SECTION              │  Call to action
│    (py-20 → py-28)          │  Gradient background
│    (bg-gradient)            │  Headline + stats
└─────────────────────────────┘
```

## Accessibility Checklist

**Before shipping any page:**

- [ ] **HTML:** Semantic elements (`<button>`, `<form>`, `<label>`)
- [ ] **Colors:** WCAG AAA contrast (4.5:1 body, 3:1 large)
- [ ] **Keyboard:** Tab, Enter, Escape all work
- [ ] **Focus:** Visible outline on all interactive elements
- [ ] **ARIA:** All buttons/forms have labels
- [ ] **Forms:** Labels associated with inputs, errors announced
- [ ] **Images:** All have meaningful alt text
- [ ] **Touch:** 44x44px minimum with 8px spacing
- [ ] **Mobile:** Zoom not disabled, responsive at 320px+
- [ ] **Screen Reader:** Test with NVDA or VoiceOver

**Testing Tools:**

- axe DevTools (browser extension - automated)
- WAVE (browser extension - errors/alerts)
- Lighthouse (Chrome DevTools - scores)
- WebAIM Contrast Checker (manual color validation)

---

## Animations

### Core Animations

- `fadeIn` - 300ms fade in from 0% to 100% opacity
- `fadeInUp` - 300ms fade + slide up 30px
- `slideInFromLeft` - 300ms slide in from -20px
- `slideInFromRight` - 300ms slide in from +20px
- `float` - 3s infinite float up/down
- `pulse` - 1.5s opacity pulse

### Timing Guidelines

- Micro-interactions: 150ms (hover effects)
- Standard transitions: 300ms (page sections)
- Intentional delays: 500ms+ (modals)
- **Motion preference:** Respect `prefers-reduced-motion` (disable animations)

### Animation Delays

```tsx
// Stagger animations for list items
{
  items.map((item, i) => (
    <div
      style={{ animationDelay: `${i * 100}ms` }}
      className="animate-fadeInUp"
    >
      {item}
    </div>
  ));
}
```

## Development Commands

### Tailwind v4 Setup

**Already Configured in `astro.config.mjs`:**

```javascript
vite: {
  plugins: [
    tailwindcss({
      content: ['./src/**/*.{astro,html,js,jsx,md,mdx,svelte,ts,tsx,vue}'],
    }),
  ],
}
```

**Global CSS Structure (in `src/styles/global.css`):**

```css
@import "tailwindcss";

@theme {
  /* Color palette */
  --color-background: 36 8% 88%;
  --color-foreground: 0 0% 13%;
  --color-primary: 216 55% 25%;
  /* ... */
}

/* Dark mode overrides */
.dark {
  --color-background: 222.2 84% 4.9%;
  /* ... */
}

/* Custom animations */
@keyframes fadeIn {
  /* ... */
}
@keyframes fadeInUp {
  /* ... */
}
```

### Component Usage

```astro
---
// src/pages/ontology/groups.astro
import Layout from '../../layouts/Layout.astro';
import DemoHero from '../../components/demo/DemoHero.astro';
import DemoPlayground from '../../components/demo/DemoPlayground.tsx';
import DemoCodeBlock from '../../components/demo/DemoCodeBlock.astro';
import DemoCTA from '../../components/demo/DemoCTA.astro';

const dimensionData = {
  hero: {
    title: 'The Groups Dimension',
    subtitle: 'Hierarchical containers for collaboration',
    // ...
  },
  // ...
};
---

<Layout title="Groups - ONE Ontology">
  <DemoHero {...dimensionData.hero} />
  <DemoPlayground {...dimensionData.playground} client:load />
  <DemoCodeBlock {...dimensionData.examples[0]} />
  <DemoCTA {...dimensionData.cta} />
</Layout>
```

---

## Design Decisions

### 1. Why Tailwind v4 CSS Variables?

**Advantages:**

- No JavaScript config file (`tailwind.config.mjs` not needed)
- Direct CSS control for design tokens
- Perfect dark mode support via CSS variables
- Smaller build size
- Easy theme customization per organization

**Implementation:**

```css
@theme {
  --color-primary: 216 55% 25%;
}

/* Usage - automatic dark mode switch */
<div class="bg-primary">Content</div>
```

### 2. Why 4px Base Grid?

**Advantages:**

- Fine control for precise spacing
- Accessible touch targets (44px = 11 x 4px)
- Responsive scalability
- Consistent with Tailwind defaults

**Scale:** 4, 8, 12, 16, 20, 24, 32, 40, 48, 64, 96, 128px

### 3. Why 5-Section Pattern?

**Because:**

- Teaches complete user journey (understand → explore → implement → visualize → act)
- Consistent across all 6 dimension pages
- Hero grabs attention
- Playground enables hands-on learning
- Code examples satisfy developers
- Graph explains relationships
- CTA drives action

### 4. Why HSL Colors?

**Advantages:**

- Easy to read: hue (0-360°) saturation (0-100%) lightness (0-100%)
- Dark mode: modify lightness only
- Accessible: easier to reason about contrast
- Tailwind v4 standard format

**Example:**

```
216 55% 25%  = Blue (hue 216) with 55% saturation, 25% lightness
CSS: hsl(216 55% 25%)
```

### 5. Why 1.125x Modular Scale?

**Typography harmony:**

- 16px (body) → 18px → 20px → 23px → 26px → 29px → 33px → 37px → 42px
- Visually balanced hierarchy
- Accessible sizing (minimum 16px body text)
- Responsive scaling on mobile

2. **Set up project:**
   - Verify Tailwind v4 in `astro.config.mjs`
   - Copy design tokens to `global.css`
   - Create directory structure `/components/demo/`

3. **Implement components:**
   - Start with `DemoContainer` (simple wrapper)
   - Then `DemoHero` (static content)
   - Then `DemoPlayground` (interactive form)
   - Continue with remaining components

4. **Test early:**
   - Run Lighthouse (Chrome DevTools)
   - Test keyboard navigation (Tab, Enter, Escape)
   - Test with screen reader (NVDA or VoiceOver)
   - Test mobile (320px viewport)

5. **Iterate:**
   - Ask Design Agent for clarification
   - Update specifications if needed
   - Share progress with team

### Success Criteria

✅ All 7 dimension pages implemented
✅ All components working
✅ Responsive at 320px, 768px, 1024px+
✅ Lighthouse 95+ (all metrics)
✅ WCAG 2.1 AA compliance (zero critical issues)
✅ Keyboard navigation working (Tab, Enter, Escape)
✅ Dark mode working (automatic color switch)
