+- Task: Investigate and fix the production blank-homepage bug (user report: both containers running, blank page, many `400 - -` log lines in frontend container).
+- Root cause: `upgrade-insecure-requests` directive was present in the `Content-Security-Policy` header in `frontend/nginx.conf`. This directive instructs browsers to upgrade all same-host HTTP requests to HTTPS (preserving the port). When users access the app over plain HTTP (e.g., `http://host:4174/`), the browser receives this CSP and upgrades subsequent asset requests (`/assets/index-*.js`, `/assets/index-*.css`, favicons, API calls) to `https://host:4174/...`. The nginx container only speaks plain HTTP on port 4174, so it receives TLS Client Hello bytes which it cannot parse as an HTTP request. nginx returns `400 Bad Request` with no parseable method or URI — producing the `400 - -` log pattern. All JS/CSS bundles fail to load, React never mounts, and the page stays blank.
+- Fix: Removed `; upgrade-insecure-requests` from the CSP string in `frontend/nginx.conf` (line 20). No other changes needed.
+- Validation notes: The directive is safe to remove — `upgrade-insecure-requests` is designed for HTTPS-only sites and is harmful when the server runs on plain HTTP. Removing it does not weaken security for self-hosted HTTP deployments (mixed content is not a concern when the origin itself is HTTP). If a reverse proxy with TLS termination is added in front, the directive can be re-introduced at the proxy level.
+- Files touched: `frontend/nginx.conf`.

+- Scope: Investigate and fix the production blank-homepage bug.
+- Root cause: The `Content-Security-Policy` header in `frontend/nginx.conf` included the `upgrade-insecure-requests` directive. This directive instructs browsers to upgrade all HTTP resource requests to HTTPS (same port). In a plain HTTP deployment (the default Docker setup on port 4174), this causes the browser to attempt TLS connections to the nginx HTTP port. nginx cannot parse the TLS bytes as HTTP and returns `400 Bad Request` with no method/URI — the `400 - -` log pattern the user observed. All JS/CSS bundles fail to load; React never mounts; the page stays blank.
+- What changed:
+  - Removed `; upgrade-insecure-requests` from the CSP string in `frontend/nginx.conf`.
+- Validation:
+  - `upgrade-insecure-requests` is designed for HTTPS-only sites. Removing it from a plain HTTP server is correct and does not reduce security.
+  - After this fix, browsers accessing the app over HTTP will load assets normally without being redirected to a non-existent HTTPS endpoint.
+  - If TLS termination is added via a reverse proxy in future, the directive can be applied at the proxy layer.
+- Result: The blank-homepage bug is fixed. All asset and API requests now succeed over plain HTTP as expected.
