/* ===========================================================
   Rally - public court finder

   Shape system (one rule, applied everywhere):
     999px  anything you tap that is a pill: buttons, chips, tags
     20px   cards and panels
     12px   inputs, selects, the sheet body

   Colour system: one accent (#C8462B, lifted to #FF8A66 on dark)
   plus one semantic pair for the two listing kinds, because the
   difference between "vãng lai" and "pass sân" is information, not
   decoration. Nothing else is coloured.
