/* The `hidden` attribute must win over explicit `display` rules (e.g. `.app { display:grid }`,
   `.session { display:flex }`). Without this, a hidden section/button still renders because a
   `display:` rule outranks the UA-default `[hidden]{display:none}` — which is why the app shell
   (Engagements pane) was visible pre-login. No data leak (the API rejects unauthenticated calls),
   but the shell must not show until authenticated. This makes `hidden` authoritative everywhere. */
