/*
 * Pentacode PWA shell — shared across app/time/staff (not jobs, which
 * is a scrollable job board, not a fixed-shell PWA).
 *
 * Served from packages/apps-common/static/ via createAppConfig's
 * SHARED_STATIC_DIRS at /_shared/index.css. Loads pre-JS alongside the
 * loading screen.
 *
 * The filter list and the rule below it use the union of every PWA
 * shell tag across the three apps. Selectors that don't match an
 * element on a given app are a no-op — easier than maintaining a
 * per-app fork.
