/* Pruma - public site (pruma.org).
   Design system v1 (handoff Claude Design, T-844): light-first, tokens.css is
   the single source of color/type/spacing - every color here is a token or a
   color-mix() derivation of one. Dark mode, if it ever comes, derives from the
   tokens later - never the reverse.
   Rule kept from day one: status color NEVER alone - icon + label always.
   The public side is calm and informative (arquitetura.md §7): no threshold
   config, statuses reduced to normal | attention (+ planned | no_data). */
