/* =============================================================================
   announcement-drawer.css — styles for the edge-docked announcement drawer.

   Own stylesheet (not site.css); every rule scoped under .announcement-drawer.
   Reuses the --hh-* design tokens from site.css's :root.

   Geometry: the container is `position: fixed` to one edge (data-position). The
   panel (card) slides in/out via `transform`; the peek tab is parked just inside
   the edge so it stays visible when collapsed. State is set by JS as the classes
   .is-peek / .is-expanded. Because the container is fixed, the parked-off-screen
   panel never adds page scroll.

   Corner rounding + X-corner + tab side all key off [data-position] so the only
   knob is the YAML `position` value. Mobile (<=640px) ignores position and uses
   a bottom sheet.

   Part of the `announcement-drawer` component:
