penpot-ui-css-404

## Description Penpot 2.14.0 at `design.optimified.com` logs a 404 for `css/ui.css?ts=2.14.0-1774340435` on every page load. The file is missing from the frontend container image — confirmed 404 on both the Railway URL (`frontend-production-9099.up.railway.app`) and the custom domain. The app is functional (login, dashboard, editor all work), but there may be subtle UI styling gaps from the missing CSS. **Expected:** `css/ui.css` loads with 200, no console errors. **Actual:** `css/ui.css` returns 404. Console shows `net::ERR_ABORTED 404 (Not Found)`. ## Steps to Reproduce 1. Open `https://design.optimified.com` in browser 2. Open DevTools → Console 3. See: `GET https://design.optimified.com/css/ui.css?ts=2.14.0-1774340435 net::ERR_ABORTED 404` ## Resolution Likely upstream Penpot issue — the HTML template references `ui.css` but the Docker image doesn't include it. Check on next Penpot version upgrade (>2.14.0) to see if resolved. If UI styling issues are noticed, investigate further.
