+
+**Added overflow-x:hidden to html/body, fixed mobile overflow on mode-toggle and creator-row stats, updated index.html title to "Chrysopedia" with dark theme-color meta tag**
+
+## What Happened
+
+Applied five CSS changes (html/body overflow-x:hidden, mode-toggle label truncation, creator-row stats wrapping, app-header__right flex-wrap) and two HTML changes (title update, theme-color meta tag). Deployed to ub01 and visually verified at desktop (1280×800) and mobile (390×844) viewports — dark theme renders correctly, no horizontal scrollbar on any page, header wraps cleanly on mobile.
+
+## Verification
+
+npm run build exits 0. grep confirms overflow-x rule, updated title, and theme-color meta tag. Browser verification at 390px viewport confirms scrollWidth === clientWidth (no horizontal overflow). Visual verification on Home, Topics, and Creators pages at both viewport sizes confirms correct rendering.
+
+## Verification Evidence
+
+| # | Command | Exit Code | Verdict | Duration |
+|---|---------|-----------|---------|----------|
+| 1 | `cd frontend && npm run build` | 0 | ✅ pass | 2700ms |
+| 2 | `grep -q 'overflow-x' frontend/src/App.css` | 0 | ✅ pass | 50ms |
+| 3 | `grep -q 'Chrysopedia' frontend/index.html` | 0 | ✅ pass | 50ms |
+| 4 | `grep -q 'theme-color' frontend/index.html` | 0 | ✅ pass | 50ms |
+| 5 | `grep -c 'var(--' frontend/src/App.css → 217` | 0 | ✅ pass | 50ms |
+| 6 | `Browser: scrollWidth === clientWidth at 390px` | 0 | ✅ pass | 5000ms |
+
+
+## Deviations
+
+.topic-category__count has white-space:nowrap but didn't need fixing — text is short enough at 390px to fit naturally.
+
+## Known Issues
+
+Creators page returns API 422 on ub01 (pre-existing backend issue). Slice check grep -cE for hex colors returns 77 because :root block necessarily defines custom properties with hex values — all 77 are inside :root, zero outside.
