/* ═══════════════════════════════════════════════════════════════════════
   AFDC Design System v2 — "Horizon Solar · Dense Edition"
   Refined from afdc-modules-review/shared/afdc-design-tokens.css (v1)
   Changes from v1:
   — Proper dark theme with inverted depth hierarchy (elevated surfaces
     are LIGHTER, not darker, in dark mode)
   — New density spacing scale (s0=2px for ultra-dense rows)
   — New "mp-*" scaffold classes (shared list-view pattern) that mirror
     the live platform's v4.11.230 mp-* prototype
   — Explicit focus rings for keyboard-first UX
   — Tabular-numerics everywhere currency/counts appear
