/* =====================================================================
   Stock Verification — design system
   ---------------------------------------------------------------------
   Built for one job: three storekeepers counting parts on a foundry
   floor, on phones, in Arabic and English.

   Decisions that follow from that:
   · Bottom navigation on phones, top navigation from 900px up.
   · Every tappable thing is at least 44x44 with room around it.
   · Part numbers and quantities are monospace with tabular figures —
     a part number is read digit by digit, not as a word.
   · Variance never relies on colour alone: a sign, a word and a colour.
     Surplus is violet, not green — finding more than the book says is
     a discrepancy, not a success.
   · Dark mode is automatic; a warehouse is not a bright office.
