/* Colour system — Voratide brand (same tokens as www.voratide.com, dark mode)
   - warm near-black neutrals for every surface and all text
   - Voratide gold for the brand mark, links, focus and selection
   - the primary action is a cream pill with navy text (www's .btn-fill)
   - data colours, muted, one meaning each, used the same everywhere
   - status colours only where something needs attention; "fine" stays neutral
   (app.js / results.js read the same values from THEME in shared.js) */
