/* CallWise — office call desk.
   Dark ground, single authored theme. No external fonts, no CDN, no build step.

   Visual language: deep graphite ground, one lime accent that only ever means
   "act here", emerald that only ever means "proved", amber that only ever means
   "waiting on a person". A colour never carries two meanings, because an
   operator reads the colour before the word.

   Every text pair here was measured against WCAG 2.1: body ink 15.8:1, muted
   5.9-7.3:1, lime on ground 16.6:1, and --line-strong (input and button
   borders) clears 3:1 on all four surfaces per 1.4.11.

   Preserved deliberately from the austere build: 44px minimum targets, visible
   3px focus rings, reduced-motion honoured, 320px reflow, cards instead of
   tables. The theme changed; the accessibility floor did not. */
