+### Web Templates & Shared Assets
+
+- HTML entrypoints live under `assets/templates/`; key files are `index.gohtml`, `app.gohtml`, `app.js.gohtml`, and `splash.gohtml`. The SPA loader logic resides in `assets/static/js/app-loader.js` and is included via `app.js.gohtml`; it performs capability checks (Promise, fetch, AbortController, `script.noModule`, etc.) before appending `window.__CONFIG__.jsUri`.
+- The same loader partial is reused in private packages (`pro/assets/templates/index.gohtml`, `plus/assets/templates/index.gohtml`). Whenever you touch `app.js.gohtml` or change how we load the bundle, mirror the update by running commands such as `cd pro && sed -n '1,160p' assets/templates/index.gohtml` (and similarly for `plus`) to confirm they include the shared partial instead of hard-coding `<script src="{{ .config.JsUri }}">`.
+- Splash styles are defined in `frontend/src/css/splash.css`. Add new splash elements (for example `.splash-warning`) there so both public and private editions remain visually consistent.
+- Browser baseline: PhotoPrism requires Safari 13 / iOS 13 or current Chrome, Edge, or Firefox. Update the message in `assets/templates/app.js.gohtml` (and the matching CSS) if support changes.

 Purpose

 - `internal/ffmpeg`, `internal/thumb`, `internal/meta`, `internal/form`, `internal/mutex` — media, thumbs, metadata, forms, coordination
 - `pkg/*` — reusable utilities (must never import from `internal/*`), e.g. `pkg/fs`, `pkg/log`, `pkg/service/http/header`
 
+Templates & Static Assets
+- Entry HTML lives in `assets/templates/index.gohtml`, which includes the splash markup from `app.gohtml` and the SPA loader from `app.js.gohtml`.
+- The loader script is implemented in `assets/static/js/app-loader.js` (included via `app.js.gohtml`) and performs capability checks (Promise, fetch, AbortController, `script.noModule`, etc.) before injecting `window.__CONFIG__.jsUri`. Update this file (and the partial) in lockstep with the templates in private repos (`pro/assets/templates/index.gohtml`, `plus/assets/templates/index.gohtml`) because they import the same partial.
+- `splash.gohtml` renders the loading screen text while the bundle loads; styles are in `frontend/src/css/splash.css`.
+- When adjusting browser support messaging, update both the loader partial and splash styles so the warning message stays consistent across editions.

 HTTP API
 - Handlers live in `internal/api/*.go` and are registered in `internal/server/routes.go`.
 - Annotate new endpoints in handler files; generate docs with: `make fmt-go swag-fmt && make swag`.

+- The HTML shell is rendered from `assets/templates/index.gohtml` (and `pro/assets/templates/index.gohtml` / `plus/...`). Each template includes `app.gohtml` for the splash markup and `app.js.gohtml` to inject the bundle.

+- Splash styles, including the `.splash-warning` fallback banner, live in `frontend/src/css/splash.css`. Keep styling changes there so public and private editions stay aligned.
+- Baseline support: Safari 13 / iOS 13 or current Chrome, Edge, or Firefox. If the support matrix changes, revise the warning text in `app.js.gohtml` and the CSS message accordingly.
