/* ==========================================================================
   SLBA design tokens — the ONLY place hex values may appear.
   Palette decisions (see slba-system-design.md §4.1–4.2):
   • Molten Orange #EC3B02 is REPLACED app-wide by the darker orange #C23200
     (passes AA for normal text on white ≈5.6:1 and white-on-orange ≈5.6:1).
   • Dusty Denim and Seashell have poor contrast: decorative/minimal use only.
     Never use them for text, and never as the background behind small text.
