/* ClearIQ — dark institutional visual identity.
   Matches Veridian Nexum's treatment: near-black, muted gold, serif
   headings (Cormorant Garamond) over a geometric sans body (Josefin Sans).

   Sprint 1.1 readability patch:
   - Body up to 20px / line-height 1.7 for extended operator reading.
   - Headings 2.5 / 2.0 / 1.5 rem, same color as body (no dimming).
   - Secondary text bumped from #8a8680 to #b8b2a5 — was below comfortable
     contrast; operator UI needs AAA-grade legibility, not marketing copy.
   - Form inputs min 18px; buttons 18px with generous padding.
