/* shared/hub_components.css — the Hub design language's reusable pieces, for EVERY app
   (TASK-439, owner 2026-09-09: the Chat & Mail app "needs a redesign from ground up based on what
   we did now with other apps"). Until today these lived in hub/www/hub_design.css and could only be
   used inside the Hub; hub_design.css now keeps only what is Hub-page-specific (page frame, hero,
   dashboard grid, auth stage) and is loaded AFTER this file by hub/www/_hub_shell.php.

   Depends on the tokens in shared/hub_topbar.css (--primary, --hub-*), which must be loaded first.
   Contents: 4. CARDS (.hub-card family, .hub-anim-in) · modal (.hub-modal*) · 6. FORMS, BUTTONS,
   ALERTS, TOGGLES (.hub-field/.hub-input/.hub-select/.hub-btn/.hub-alert/.hub-toggle …).
   No app-specific rule belongs here (owner rule: one shared CSS source, no forks). */
