/* shared/hub_topbar.css — the Hub's floating glass top bar, and the design tokens it uses.
   TASK-439 (owner, 2026-09-09): "Could it be possible that we have this Hub's header menu in every
   of our satellite apps, but it's automatically hidden on the top and just drops down when a user
   goes up with a mouse?" — so the bar (markup: shared/hub_topbar.php) and its CSS moved out of
   hub/www/hub_design.css into shared/, where every app can load them. hub_design.css keeps the
   rest of the Hub design and is loaded AFTER this file by hub/www/_hub_shell.php.

   Two modes, one markup:
     · Hub pages: sticky bar at the top of the page (as before)
     · satellite apps: `.hub-topbar--peek` — fixed, parked above the viewport, slides down while
       the pointer is at the top edge (`.hub-topbar__hot`) or on the bar; never on touch layouts
       (the shared bottom drawer owns ≤1024px).
   No app-specific rule belongs here (owner rule: one shared CSS source, no forks). */
