Homelable could only own the root of an origin. Behind an existing proxy at `https://home.example/homelab/` the built `index.html` still asked for `/assets/*`, which fell through to whatever owned the root — and when that answered `text/html` for a `<script>` under `nosniff`, the browser failed the load on an HTTP 200. The only workaround was patching the checkout and rebuilding on every upgrade. One build-time knob, `VITE_BASE_PATH`, becomes Vite's `base`. Vite rewrites the asset URLs it emits; everything the app builds by hand goes through the new `utils/basePath.ts` — the axios instances, the WebSocket URL, the live-view route, the local brand icons, and the OIDC login href. `resolveServerPath` covers what the *backend* hands back, which is always root-absolute because it cannot know where the SPA is mounted: uploaded floor-plan URLs already stored in a canvas are resolved at render time, so plans predating the move keep loading. The OIDC callback used to redirect to `/`, dropping subpath users at the origin root after login; it now reads the prefix back out of `OIDC_REDIRECT_URI`. The default is `/`, and stays a no-op there by construction: every helper returns the string it returned before, the root build output is unchanged and both nginx sites are byte-identical to what shipped — the Docker image copies `docker/nginx.conf` verbatim and the installer keeps its original heredoc. Only a non-default prefix takes the generated config. Those generated configs use `root`, never `alias`, since `alias` plus `try_files` mis-resolves `$uri` — the Docker build lands the bundle in the matching subdirectory, and the installer symlinks it under `/var/www/homelable`. Both accept either reverse-proxy style, prefix forwarded intact or already stripped, with no redirect loop between them, and `absolute_redirect off` stops the no-slash 301 from eating the port. Closes #334. ha-relevant: maybe
