/* =========================================================================
   S2 · the live player's styles: the mini bar, the drawer, the card buttons.

   Every value is a token from design-tokens.css: this file is under the B-1
   ad-hoc-CSS ratchet (tests/test_design_tokens.py), and it states no colour and
   no px/rem/em literal of its own.  Sizes come from the spacing scale, type
   from the type scale, elevation from the shadow scale — the player is a
   *surface*, and it looks like the rest of the shell because of that.

   Layout: the mini bar floats directly above the tab bar (same insets, one
   step up), so on a phone nothing covers it and it covers nothing.  The drawer
   is a full-screen overlay at the overlay z-step, and it is the only surface
   the player raises above the shell.
