+- Landing page (`site/index.html`): external CSS/JS, SEO (dashboard screenshot, manifest, sitemap.xml), security panel, aligned copy and Octicons.
+- Landing preview on mobile (`site/index.html`, `site/css/index.css`): proportional dashboard scale (full screenshot visible), no horizontal scroll; fine-tuned tentacle positions/sizes on small screens only (desktop layout unchanged).
 - Download page (`site/download.html`): static manifest, shared nav styles via `common.css`, centered OS picker, clearer prerequisites, tighter install steps.
 - README header uses `site/gitdock-logo-removebg-preview.png` (transparent logo for GitHub light and dark themes).
 - `server.js` imports validation helpers from `lib/` (behavior preserved; easier to test).

+## Summary
+
+Fixes the landing page product preview on mobile: the full dashboard screenshot stays visible at proportional scale, horizontal scroll is removed, and tentacle placement is tuned for small screens without changing desktop layout or image assets.
+
+## Type of change
+
+- [x] Documentation / site only
+
+## What changed
+
+- **`site/index.html`:** `.preview-stage` wrapper; mobile `@media` uses single `zoom` scale (with `transform` fallback); per-tentacle tweaks only where needed (left pair, front pair, right tentacle).
+- **`site/css/index.css`:** `.preview-stage` desktop wrapper; removed dead per-tentacle rules that never applied (inline CSS wins); mobile `overflow-x: clip` on preview/html/body.
+- **`.gitattributes`:** `text=auto eol=lf` so Windows/Cursor do not flip line endings on every save.
+
+## Release
+
+**No GitHub Release or version bump.** Site-only change (redeploy `site/` when you publish the site).
+
+## Checklist
+
+- [x] Site-only — `npm test` not required for this PR
+- [x] Smoke-tested preview at `http://localhost:3848/` (desktop + mobile ~390px)
+- [x] No secrets in commits
+- [x] Updated `CHANGELOG.md` under **Unreleased**
+
+## Test plan
+
+- [x] Desktop (~1280px): preview matches pre-change layout; tentacles and dashboard unchanged
+- [x] Mobile (390px): full dashboard visible, no horizontal scroll
+- [x] Tentacles: left pair separated; front pair sized/spaced; right tentacle lower, behind dashboard
+- [ ] After deploy: spot-check https://www.gitdock.dev/ on phone or DevTools
