/* ═══════════════════════════════════════════════════════════════════════════
   灶前 ZO CHIN — restaurant demo
   ---------------------------------------------------------------------------
   Art direction: a service pass. The page is built like the ticket rail in a
   kitchen — a split hero with the room's live state on the right, then ruled
   ledgers rather than cards, because a menu and a table list are both lists
   that change daily and have to be editable in thirty seconds.

   Deliberately unlike the other demos in the set: it is the only one with a
   sticky action bar, the only one whose hero is a two-column split, and the
   only one that uses a warm oxblood ground. A restaurant page that looked like
   the coffee page would tell a prospect we have one layout.

   This demo keeps its CSS in a FILE rather than inline, because it is a
   multi-page demo — index, menu and booking share it. The single-page demos
   keep their styles inline, which is right for one file and wrong for three.
