Consolidate shared UI assets

Move common logo and controller glyphs into `ui/views/CommonwealthOnline/shared/` and update the pause menu, main menu, and browser glyph loader to use the shared paths. Also add a sync script and update deploy/staging scripts to copy controller icons once into the shared folder.

+## 2026-07-05 - Shared UI Assets Folder
+
+### Summary
+Moved cross-view assets (logo, controller glyph icons) into `ui/views/CommonwealthOnline/shared/`. All PrismaUI views now reference this single folder instead of requiring per-view icon copies.
+
+### Files Changed
+- `ui/views/CommonwealthOnline/shared/` (logo.svg, logo.png, icons/)
+- `ui/views/CommonwealthOnline/pause-menu/index.html`
+- `ui/views/CommonwealthOnline/main-menu/index.html`
+- `ui/views/CommonwealthOnline/browser/components/controller-glyphs.js`
+- `ui/views/CommonwealthOnline/pause-menu/styles.css`
+- `deploy-ui.bat`
+- `stage-mod.bat`
+- `ui/sync-shared-assets.bat`
+- `changelog.md`
+- `docs/dev-log.md`
+
+### Details
+- Deploy scripts copy `ui/Icons` once into `shared/icons/` instead of browser, pause-menu, and main-menu separately
+- `ui/sync-shared-assets.bat` populates shared icons for local HTML preview without deploying to the game
+
+### Testing
+- Run `ui/sync-shared-assets.bat` (or `deploy-ui.bat`)
+- Open `main-menu/index.html` and `pause-menu/index.html` in a browser; confirm controller glyphs tint amber/green
+- Open server browser; confirm footer glyphs still load
+
+### Known Issues
+- `shared/icons/` is populated by sync/deploy scripts; it is not checked into git as a second copy of `ui/Icons`
+
+### Next Steps
+- None for asset layout
+
+## 2026-07-05 - Main Menu UI Concept Prototype
+
+### Summary
+Added a static HTML/CSS/JS main menu prototype matching the pause menu visual language, without map mode or server panel. Menu includes MULTIPLAYER, CREATIONS, SETTINGS, HELP, and QUIT. Embeds the shared `CO_Settings` module for the settings sub-view.
+
+### Files Changed
+- `ui/views/CommonwealthOnline/main-menu/index.html`
+- `ui/views/CommonwealthOnline/main-menu/styles.css`
+- `ui/views/CommonwealthOnline/main-menu/script.js`
+- `deploy-ui.bat`
+- `stage-mod.bat`
+- `changelog.md`
+- `docs/dev-log.md`
+
+### Details
+- Scenic CSS gradient background replaces the pause menu map layer
+
+### Testing
+- Open `ui/views/CommonwealthOnline/main-menu/index.html` in a browser at 1920×1080
+- Arrow keys / click to navigate menu; confirm rows are MULTIPLAYER, CREATIONS, SETTINGS, HELP, QUIT
+- Select SETTINGS; confirm embedded settings panel opens and B/Escape returns to menu
+- Resize window; confirm `--co-ui-scale` keeps layout proportional
+
+### Known Issues
+- Background is a CSS placeholder, not a captured Fallout 4 title-screen image
+- Not wired to F4SE/PrismaUI yet (concept prototype only)
+
+### Next Steps
+- Hook main menu into PrismaUI and replace vanilla title-screen list when ready
