## Project Structure

### Assets (Universal)

All frameworks use the same asset organization:

```
assets/
├── images/
│   ├── hero-landing-1710xxx.webp
│   ├── icon-feature-01.webp
│   └── bg-pattern.svg
├── videos/
│   ├── hero-bg-1710xxx.mp4
│   └── demo-preview.mp4
└── audio/
    ├── bgm-ambient-1710xxx.mp3
    └── tts-intro-1710xxx.mp3
```

**Asset naming:** `{type}-{descriptor}-{timestamp}.{ext}`

### By Framework

| Framework | Asset Location | Component Location |
|-----------|---------------|-------------------|
| **Pure HTML** | `./assets/` | N/A (inline or `./js/`) |
| **React/Next.js** | `public/assets/` | `src/components/` |
| **Vue/Nuxt** | `public/assets/` | `src/components/` |
| **Svelte/SvelteKit** | `static/assets/` | `src/lib/components/` |
| **Astro** | `public/assets/` | `src/components/` |

### Pure HTML

```

## Compliance

**All rules in this skill are mandatory. Violating any rule is a blocking error — fix before proceeding or delivering.**

---

## Workflow
### Phase 1: Design Architecture
1. Analyze the request — determine page type and context
2. Set design dials based on page type
3. Plan layout sections and identify asset needs

### Phase 2: Motion Architecture
1. Select animation tools per section (see Tool Selection Matrix)
2. Plan motion sequences following performance guardrails

### Phase 3: Asset Generation
Generate all image/video/audio assets using `scripts/`. NEVER use placeholder URLs (unsplash, picsum, placeholder.com, via.placeholder, placehold.co, etc.) or external URLs.

1. Parse asset requirements (type, style, spec, usage)
2. Craft optimized prompts, show to user, confirm before generating
3. Execute via scripts, save to project — do NOT proceed to Phase 5 until all assets are saved locally

### Phase 4: Copywriting & Content
Follow copywriting frameworks (AIDA, PAS, FAB) to craft all text content. Do NOT use "Lorem ipsum" — write real copy.

### Phase 5: Build UI
Scaffold the project and build each section following Design and Motion rules. Integrate generated assets and copy. All `<img>`, `<video>`, `<source>`, and CSS `background-image` MUST reference local assets from Phase 3.

### Phase 6: Quality Gates
Run final checklist (see Quality Gates section).

---

# 1. Design Engineering

## 1.1 Baseline Configuration

| Dial | Default | Range |
|------|---------|-------|
| DESIGN_VARIANCE | 8 | 1=Symmetry, 10=Asymmetric |
| MOTION_INTENSITY | 6 | 1=Static, 10=Cinematic |
| VISUAL_DENSITY | 4 | 1=Airy, 10=Packed |

Adapt dynamically based on user requests.

## 1.2 Architecture Conventions
- **DEPENDENCY VERIFICATION:** Check `package.json` before importing any library. Output install command if missing.
- **Framework:** React/Next.js. Default to Server Components. Interactive components must be isolated `"use client"` leaf components.
- **Styling:** Tailwind CSS. Check version in `package.json` — NEVER mix v3/v4 syntax.
- **ANTI-EMOJI POLICY:** NEVER use emojis anywhere. Use Phosphor or Radix icons only.
- **Viewport:** Use `min-h-[100dvh]` not `h-screen`. Use CSS Grid not flex percentage math.
- **Layout:** `max-w-[1400px] mx-auto` or `max-w-7xl`.

## 1.3 Design Rules
| Rule | Directive |
|------|-----------|
| Typography | Headlines: `text-4xl md:text-6xl tracking-tighter`. Body: `text-base leading-relaxed max-w-[65ch]`. **NEVER** use Inter — use Geist/Outfit/Satoshi. **NEVER** use Serif on dashboards. |
| Color | Max 1 accent, saturation < 80%. **NEVER** use AI purple/blue. Stick to one palette. |
| Layout | **NEVER** use centered heroes when VARIANCE > 4. Force split-screen or asymmetric layouts. |
| Cards | **NEVER** use generic cards when DENSITY > 7. Use `border-t`, `divide-y`, or spacing. |
| States | **ALWAYS** implement: Loading (skeleton), Empty, Error, Tactile feedback (`scale-[0.98]`). |
| Forms | Label above input. Error below. `gap-2` for input blocks. |

## 1.4 Anti-Slop Techniques

- **Liquid Glass:** `backdrop-blur` + `border-white/10` + `shadow-[inset_0_1px_0_rgba(255,255,255,0.1)]`
- **Magnetic Buttons:** Use `useMotionValue`/`useTransform` — never `useState` for continuous animations
- **Perpetual Motion:** When INTENSITY > 5, add infinite micro-animations (Pulse, Float, Shimmer)
- **Layout Transitions:** Use Framer `layout` and `layoutId` props
- **Stagger:** Use `staggerChildren` or CSS `animation-delay: calc(var(--index) * 100ms)`

## 1.5 Forbidden Patterns
| Category | Banned |
|----------|--------|
| Visual | Neon glows, pure black (#000), oversaturated accents, gradient text on headers, custom cursors |
| Typography | Inter font, oversized H1s, Serif on dashboards |
| Layout | 3-column equal card rows, floating elements with awkward gaps |
| Components | Default shadcn/ui without customization |

## 1.6 Creative Arsenal

| Category | Patterns |
|----------|----------|
| Navigation | Dock magnification, Magnetic button, Gooey menu, Dynamic island, Radial menu, Speed dial, Mega menu |
| Layout | Bento grid, Masonry, Chroma grid, Split-screen scroll, Curtain reveal |
| Cards | Parallax tilt, Spotlight border, Glassmorphism, Holographic foil, Swipe stack, Morphing modal |
| Scroll | Sticky stack, Horizontal hijack, Locomotive sequence, Zoom parallax, Progress path, Liquid swipe |
| Gallery | Dome gallery, Coverflow, Drag-to-pan, Accordion slider, Hover trail, Glitch effect |
| Text | Kinetic marquee, Text mask reveal, Scramble effect, Circular path, Gradient stroke, Kinetic grid |
| Micro | Particle explosion, Pull-to-refresh, Skeleton shimmer, Directional hover, Ripple click, SVG draw, Mesh gradient, Lens blur |

## 1.7 Bento Paradigm

- **Palette:** Background `#f9fafb`, cards pure white with `border-slate-200/50`
- **Surfaces:** `rounded-[2.5rem]`, diffusion shadow
- **Typography:** Geist/Satoshi, `tracking-tight` headers
- **Labels:** Outside and below cards
- **Animation:** Spring physics (`stiffness: 100, damping: 20`), infinite loops, `React.memo` isolation

**5-Card Archetypes:**
1. Intelligent List — auto-sorting with `layoutId`
2. Command Input — typewriter + blinking cursor
3. Live Status — breathing indicators
4. Wide Data Stream — infinite horizontal carousel
5. Contextual UI — staggered highlight + float-in toolbar

## 1.8 Brand Override

When brand styling is active:
- Dark: `#141413`, Light: `#faf9f5`, Mid: `#b0aea5`, Subtle: `#e8e6dc`
- Accents: Orange `#d97757`, Blue `#6a9bcc`, Green `#788c5d`
- Fonts: Poppins (headings), Lora (body)

---

# 2. Motion Engine

## 2.1 Tool Selection Matrix

| Need | Tool |
|------|------|
| UI enter/exit/layout | **Framer Motion** — `AnimatePresence`, `layoutId`, springs |
| Scroll storytelling (pin, scrub) | **GSAP + ScrollTrigger** — frame-accurate control |
| Looping icons | **Lottie** — lazy-load (~50KB) |
| 3D/WebGL | **Three.js / R3F** — isolated `<Canvas>`, own `"use client"` boundary |
| Hover/focus states | **CSS only** — zero JS cost |
| Native scroll-driven | **CSS** — `animation-timeline: scroll()` |

**Conflict Rules [MANDATORY]:**
- NEVER mix GSAP + Framer Motion in same component
- R3F MUST live in isolated Canvas wrapper
- ALWAYS lazy-load Lottie, GSAP, Three.js

## 2.2 Intensity Scale

| Level | Techniques |
|-------|------------|
| 1-2 Subtle | CSS transitions only, 150-300ms |
| 3-4 Smooth | CSS keyframes + Framer animate, stagger ≤3 items |
| 5-6 Fluid | `whileInView`, magnetic hover, parallax tilt |
| 7-8 Cinematic | GSAP ScrollTrigger, pinned sections, horizontal hijack |
| 9-10 Immersive | Full scroll sequences, Three.js particles, WebGL shaders |

## 2.3 Animation Recipes

See `references/motion-recipes.md` for full code. Summary:

| Recipe | Tool | Use For |
|--------|------|---------|
| Scroll Reveal | Framer | Fade+slide on viewport entry |
| Stagger Grid | Framer | Sequential list animations |
| Pinned Timeline | GSAP | Horizontal scroll with pinning |
| Tilt Card | Framer | Mouse-tracking 3D perspective |
| Magnetic Button | Framer | Cursor-attracted buttons |
| Text Scramble | Vanilla | Matrix-style decode effect |
| SVG Path Draw | CSS | Scroll-linked path animation |
| Horizontal Scroll | GSAP | Vertical-to-horizontal hijack |
| Particle Background | R3F | Decorative WebGL particles |
| Layout Morph | Framer | Card-to-modal expansion |

## 2.4 Performance Rules
**GPU-only properties (ONLY animate these):** `transform`, `opacity`, `filter`, `clip-path`

**NEVER animate:** `width`, `height`, `top`, `left`, `margin`, `padding`, `font-size` — if you need these effects, use `transform: scale()` or `clip-path` instead.

**Isolation:**
- Perpetual animations MUST be in `React.memo` leaf components
- `will-change: transform` ONLY during animation
- `contain: layout style paint` on heavy containers

**Mobile:**
- ALWAYS respect `prefers-reduced-motion`
- ALWAYS disable parallax/3D on `pointer: coarse`
- Cap particles: desktop 800, tablet 300, mobile 100
- Disable GSAP pin on mobile < 768px

**Cleanup:** Every `useEffect` with GSAP/observers MUST `return () => ctx.revert()`

## 2.5 Springs & Easings

| Feel | Framer Config |
|------|---------------|
| Snappy | `stiffness: 300, damping: 30` |
| Smooth | `stiffness: 150, damping: 20` |
| Bouncy | `stiffness: 100, damping: 10` |
| Heavy | `stiffness: 60, damping: 20` |

| CSS Easing | Value |
|------------|-------|
| Smooth decel | `cubic-bezier(0.16, 1, 0.3, 1)` |
| Smooth accel | `cubic-bezier(0.7, 0, 0.84, 0)` |
| Elastic | `cubic-bezier(0.34, 1.56, 0.64, 1)` |

## 2.6 Accessibility
- ALWAYS wrap motion in `prefers-reduced-motion` check
- NEVER flash content > 3 times/second (seizure risk)
- ALWAYS provide visible focus rings (use `outline` not `box-shadow`)
- ALWAYS add `aria-live="polite"` for dynamically revealed content
- ALWAYS include pause button for auto-playing animations

## 2.7 Dependencies

```bash
npm install framer-motion           # UI (keep at top level)
npm install gsap                    # Scroll (lazy-load)
npm install lottie-react            # Icons (lazy-load)
npm install three @react-three/fiber @react-three/drei  # 3D (lazy-load)
```

# 3. Asset Generation

## 3.1 Scripts

| Type | Script | Pattern |
|------|--------|---------|
| TTS | `scripts/minimax_tts.py` | Sync |
| Music | `scripts/minimax_music.py` | Sync |
| Video | `scripts/minimax_video.py` | Async (create → poll → download) |
| Image | `scripts/minimax_image.py` | Sync |

Env: `MINIMAX_API_KEY` (required).

## 3.2 Workflow
1. **Parse:** type, quantity, style, spec, usage
2. **Craft prompt:** Be specific (composition, lighting, style). **NEVER** include text in image prompts.
3. **Execute:** Show prompt to user, **MUST confirm before generating**, then run script
4. **Save:** `<project>/public/assets/{images,videos,audio}/` as `{type}-{descriptor}-{timestamp}.{ext}` — **MUST save locally**
5. **Post-process:** Images → WebP, Videos → ffmpeg compress, Audio → normalize
6. **Deliver:** File path + code snippet + CSS suggestion

## 3.3 Preset Shortcuts

| Shortcut | Spec |
|----------|------|
| `hero` | 16:9, cinematic, text-safe |
| `thumb` | 1:1, centered subject |
| `icon` | 1:1, flat, clean background |
| `avatar` | 1:1, portrait, circular crop ready |
| `banner` | 21:9, OG/social |
| `bg-video` | 768P, 6s, `[Static shot]` |
| `video-hd` | 1080P, 6s |
| `bgm` | 30s, no vocals, loopable |
| `tts` | MiniMax HD, MP3 |

## 3.4 Reference

- `references/minimax-cli-reference.md` — CLI flags
- `references/asset-prompt-guide.md` — Prompt rules
- `references/minimax-voice-catalog.md` — Voice IDs
- `references/minimax-tts-guide.md` — TTS usage

# 4. Copywriting

## 4.1 Core Job

1. Grab attention → 2. Create desire → 3. Remove friction → 4. Prompt action

## 4.2 Frameworks

**AIDA** (landing pages, emails):
```
ATTENTION:  Bold headline (promise or pain)
INTEREST:   Elaborate problem ("yes, that's me")
DESIRE:     Show transformation
ACTION:     Clear CTA
```

**PAS** (pain-driven products):
```
PROBLEM:    State clearly
AGITATE:    Make urgent
SOLUTION:   Your product
```

**FAB** (product differentiation):
```
FEATURE:    What it does
ADVANTAGE:  Why it matters
BENEFIT:    What customer gains
```

## 4.3 Headlines

| Formula | Example |
|---------|---------|
| Promise | "Double open rates in 30 days" |
| Question | "Still wasting 10 hours/week?" |
| How-To | "How to automate your pipeline" |
| Number | "7 mistakes killing conversions" |
| Negative | "Stop losing leads" |
| Curiosity | "The one change that tripled bookings" |
| Transformation | "From 50 to 500 leads" |

Be specific. Lead with outcome, not method.

## 4.4 CTAs

**Bad:** Submit, Click here, Learn more

**Good:** "Start my free trial", "Get the template now", "Book my strategy call"

**Formula:** [Action Verb] + [What They Get] + [Urgency/Ease]

Place: above fold, after value, multiple on long pages.

## 4.5 Emotional Triggers

| Trigger | Example |
|---------|---------|
| FOMO | "Only 3 spots left" |
| Fear of loss | "Every day without this, you're losing $X" |
| Status | "Join 10,000+ top agencies" |
| Ease | "Set it up once. Forget forever." |
| Frustration | "Tired of tools that deliver nothing?" |
| Hope | "Yes, you CAN hit $10K MRR" |

## 4.6 Objection Handling

| Objection | Response |
|-----------|----------|
| Too expensive | Show ROI: "Pays for itself in 2 weeks" |
| Won't work for me | Social proof from similar customer |
| No time | "Setup takes 10 minutes" |
| What if it fails | "30-day money-back guarantee" |
| Need to think | Urgency/scarcity |

Place in FAQ, testimonials, near CTA.

## 4.7 Proof Types

Testimonials (with name/title), Case studies, Data/metrics, Social proof, Certifications

---

# 5. Visual Art

Philosophy-first workflow. Two output modes.

## 5.1 Output Modes

| Mode | Output | When |
|------|--------|------|
| Static | PDF/PNG | Posters, print, design assets |
| Interactive | HTML (p5.js) | Generative art, explorable variations |

## 5.2 Workflow

### Step 1: Philosophy Creation
Name the movement (1-2 words). Articulate philosophy (4-6 paragraphs) covering:
- Static: space, form, color, scale, rhythm, hierarchy
- Interactive: computation, emergence, noise, parametric variation

### Step 2: Conceptual Seed
Identify subtle, niche reference — sophisticated, not literal. Jazz musician quoting another song.

### Step 3: Creation

**Static Mode:**
- Single page, highly visual, design-forward
- Repeating patterns, perfect shapes
- Sparse typography from `canvas-fonts/`
- Nothing overlaps, proper margins
- Output: `.pdf` or `.png` + philosophy `.md`

**Interactive Mode:**
1. Read `templates/viewer.html` first
2. Keep FIXED sections (header, sidebar, seed controls)
3. Replace VARIABLE sections (algorithm, parameters)
4. Seeded randomness: `randomSeed(seed); noiseSeed(seed);`
5. Output: single self-contained HTML

### Step 4: Refinement
Refine, don't add. Make it crisp. Polish into masterpiece.
