   bars-tour.css — the /bars playable product tour
   ============================================================================
   Page-specific layout and the two things that genuinely cannot live in the
   shared system: the paper merchant copy, and the printed table card.

   EVERY value here resolves to a token from vetra.css. There are no raw hex
   colours, no font sizes outside the six-step scale, and no radii outside the
   three. The two exceptions are called out where they appear and are physical
   object colours — paper and ballpoint ink are not part of a UI theme and must
   not invert with it.
