/* ==========================================================================
   RestoFlow UI
   --------------------------------------------------------------------------
   Design notes (deliberate, not defaults):
   - No web fonts. A restaurant tablet on shaky wifi should never wait on a
     font download before a waiter can punch an order. System stack only.
   - Money is set in tabular figures everywhere. A POS lives on columns of
     numbers lining up; that is the signature of this interface.
   - The veg / non-veg square marker is the real vernacular of an Indian menu
     card, so it is the item identity marker here too — not a colour chip.
   - Touch targets are 44px minimum. Thumbs, not mice.
