   theme.css - AlphaDrill single authoritative design system.

   Loaded LAST (after exam.css, polish.css, alphadrill.css). Every visual
   decision lives here. The three earlier files handle the exam runner skin
   (exam.html loads only exam.css + polish.css + alphadrill.css; no theme.css).
   For all other pages this file is the final word.

   Design language: calm finance-premium - "expensive fintech / Linear".
   One deep-ink neutral palette, ONE refined emerald accent, 8-px grid,
   generous whitespace, real hierarchy, no emoji.
