/* =========================================================
   includes/console.css — VioLev "Adventure / Labs" → Console

   /adventure/console/ — the CONG-INC company store, as a working
   point-of-sale. Two live panes on one screen:
     · REGISTER (left)    — the cashier's face: catalog → ticket → tender → receipt
     · BACK OFFICE (right) — the catalog CRUD + tax rate that FEEDS the register

   Both read and write one in-memory state object; any edit re-renders
   both panes, so a change in back office shows in the register instantly.
   Nothing is saved — refresh wipes it (the point: we keep nothing).

   Shell: the same fit-to-viewport single screen as the Locator (body is
   100dvh flex column via adventure.css). The page never scrolls; each
   pane is its own min-height:0 flex child that scrolls internally.

   A POS is software — it legitimately needs JS. PHP still renders the
   catalog as a static price list for no-JS visitors (the DATA degrades
   gracefully; the APPLICATION asks for JS), styled at the bottom here.
