+### 2026-01-20 — Phase 8 Complete (Полировка)
+- ✅ **Stagger Animation:** `@keyframes bentoFadeIn` (fade-in + translateY(16px→0))
+- ✅ **CSS Variable `--stagger`:** Для delay между карточками (50ms increments)
+- ✅ **Micro-interactions:**
+  - Hover: `translateY(-4px)` + enhanced shadow
+  - Active: `scale(0.98)` + faster transition (150ms)
+- ✅ **Custom Scrollbar:** 6px thin, dark-700 thumb, transparent track
+- ✅ **Accessibility:** `prefers-reduced-motion` disables animations
+- ✅ **Light Theme:** Matching hover/active states for `.light` mode
+
+**Использование stagger в JSX:**
+```jsx
+<div className="bento-card" style={{ '--stagger': 0 }}>Card 1</div>
+<div className="bento-card" style={{ '--stagger': 1 }}>Card 2</div>
+<div className="bento-card" style={{ '--stagger': 2 }}>Card 3</div>
+```
+
 ### 2026-01-20 — Phase 7 Complete (Header + Font)
 - ✅ **Шрифт:** Urbanist → Manrope (Google Fonts, tailwind.config.js, globals.css)
 - ✅ **Header Container:** `glass` + `shadow-lg shadow-black/10` (убран border-b)
