/* EnaChat — citizen-facing public chat site tokens.
   Source of truth: the Claude Design project «Xat public — entrada 1c a
   resposta 1e» (enachat/design/Xat public - entrada 1c a resposta 1e.dc.html)
   distilled in DESIGN.md → «Citizen-facing public chat». This is the ONLY
   file on the public surface allowed to hold bare hex; components reference
   var(--…). Per-town theming: the page sets --primary/--on-primary/
   --primary-ink inline from theme_vars(town.primary_color) (contrast-safe).

   Fonts are self-hosted (zero third-party requests on citizen pages):
   Libre Franklin (UI, variable 400–700) + Source Serif 4 (ONLY the question
   heading: a static weight-600 instance subset with fonttools — 41 KB, not the
   122 KB variable font). */
