/*
* Shared authenticated app-shell styling — the header rendered into
* #appIdentityBar and the nav rendered into #appRoleNav by
* static/app-shell.js, one stylesheet for all seven primary pages
* (linked from each page's own , see static/*.html).
*
* Loaded as a real rather than injected by JS: a
* in is applied before the page renders, so the moment
* app-shell.js creates the header/nav DOM (after its own /api/session
* fetch resolves) it is already styled — no flash of unstyled/oversized
* content while JS-injected rules would still be racing the first paint.
*
* Coordinates with each page's own dark header theme (--ink/--paper/
* --amber custom properties, already defined in every page's own
