/* ══════════════════════════════════════════════════════════════
   KEEL — options desk. LIGHT. Dense, instrument-grade, numbers-first.

   Design notes for the light pass:
   • The dark theme got hierarchy free from luminance. On paper it has to
     be rebuilt from four things instead: a grey GROUND with white PANELS,
     hairline RULES, restrained surface TINTS, and TYPE WEIGHT.
   • Ground is #eef1f5 (cool paper), panels are white. Panels therefore
     read as lifted without needing a card shadow beyond a 1px hint.
   • Every semantic colour is picked to clear 4.5:1 on white, so P&L stays
     legible without shouting. Verified ratios are noted inline.
