## Style Guidelines

**Style:** Minimalism & Swiss Style

**Keywords:** Clean, simple, spacious, functional, white space, high contrast, geometric, sans-serif, grid-based, essential

**Best For:** Enterprise apps, dashboards, documentation sites, SaaS platforms, professional tools

**Key Effects:** Subtle hover (200-250ms), smooth transitions, sharp shadows if any, clear type hierarchy, fast loading

### Page Pattern

**Pattern Name:** Scroll-Triggered Storytelling

- **Conversion Strategy:** Keep the narrative understandable without scroll-driven effects. Use progress indicator. Mobile: simplify animations. Keep DOM reading order complete; disable parallax and scroll-scrub under reduced motion. Pause scroll animation when offscreen or hidden and render each chapter in its final readable state under reduced motion.
- **CTA Placement:** End of each chapter (mini) + Final climax CTA
- **Section Order:** Intro hook > Chapter 1 (problem) > Chapter 2 (journey) > Chapter 3 (solution) > Climax CTA

---

## Motion

**Scroll Reveal** (Subtle) — Trigger: scroll (viewport enter) | Duration: 300-400ms | Easing: `power1.out`

```js
gsap.from(el, { opacity: 0, y: 12, duration: 0.35, ease: 'power1.out', scrollTrigger: { trigger: el, start: 'top 90%', toggleActions: 'play none none reverse' } });
```

**Framework notes:** Requires the ScrollTrigger plugin registered once via gsap.registerPlugin(ScrollTrigger); Use matchMedia('(prefers-reduced-motion: reduce)') to skip non-essential motion and render the final state immediately

- ✅ Keep the y offset small (8-16px) so it reads as a fade, not a slide
- ❌ Don't reveal below-the-fold content needed for SEO/crawlers as invisible-by-default without a no-JS fallback
- ⚡ toggleActions 'play none none reverse' avoids re-triggering on every scroll direction change

---

## Anti-Patterns (Do NOT Use)

- ❌ Cheap visuals
- ❌ Fast animations

### Additional Forbidden Patterns

- ❌ **Emojis as icons** — Use SVG icons (Heroicons, Lucide, Simple Icons)
- ❌ **Missing cursor:pointer** — All clickable elements must have cursor:pointer
- ❌ **Layout-shifting hovers** — Avoid scale transforms that shift layout
- ❌ **Low contrast text** — Maintain 4.5:1 minimum contrast ratio
- ❌ **Instant state changes** — Always use transitions (150-300ms)
- ❌ **Invisible focus states** — Focus states must be visible for a11y
