/* ============================================================================
   PenToPill — design system
   ----------------------------------------------------------------------------
   Built for a pharmacist standing at a counter with a customer waiting: a phone
   or tablet held one-handed, under hard fluorescent light, often with wet or
   gloved hands. That sets the rules the rest of this file follows.

     Colour carries clinical meaning ONLY. Teal / amber / red mean high /
     check-carefully / low confidence and nothing else, so a coloured thing on
     screen is always a thing to think about. Commercial information — price,
     savings, cheapest — is deliberately monochrome and typographic, because a
     green price tag next to a green confidence band would teach the eye to read
     "cheap" as "safe".

     Touch targets are 44px minimum. Prices are tabular so a column of them can
     be scanned rather than read.

   One token block. There is no second :root further down overriding this one.
