 #### FR-023: Scroll Animations
 
-`IntersectionObserver` via `ScrollObserver` `#[island]` as the baseline implementation (works in all browsers). A single island instance observes all `.reveal` / `.reveal-left` / `.reveal-right` / `.reveal-scale` elements and adds `.visible` on intersection. CSS `animation-timeline: scroll()` as progressive enhancement for Chromium browsers. Motion style: fade-up and slide-in, smooth and organic. Respects `prefers-reduced-motion` — all animations disabled when set.
+Scroll reveal is handled by an inline `<script>` in the HTML shell (`src/app.rs`), not a WASM island. The previous `ScrollObserver` `#[island]` approach was replaced because it blocked SSR content — all `.reveal` elements remained invisible until WASM hydrated, defeating the purpose of pre-rendering.
+
+The inline script implementation:
+
+- **Above-fold elements** are revealed synchronously via `getBoundingClientRect()` viewport check (no transition delay, content visible on first paint)
+- **Below-fold elements** are animated via `IntersectionObserver` as they scroll into view
+- **SPA route changes** are handled by a `MutationObserver` that re-scans for new `.reveal` elements
+- **No-JS fallback**: a `<noscript><style>` block makes all `.reveal` content visible without JavaScript
+
+Supports `.reveal`, `.reveal-left`, `.reveal-right`, `.reveal-scale` classes, adding `.visible` on intersection. CSS `animation-timeline: scroll()` remains as progressive enhancement for Chromium browsers. Motion style: fade-up and slide-in, smooth and organic. Respects `prefers-reduced-motion` — all animations disabled when set.
