   ------------------------------------------------------------
   Every page links this file. To rebrand the whole site, edit
   the CANONICAL PRIMITIVES block below. Everything else is an
   alias or a derived value that follows the primitives, so a
   palette or font swap here propagates to all six pages and to
   the particle-field background.

   2026-06-03: three older per-page palettes (event / recap /
   report) were merged into one brand. Legacy token names from
   those palettes (--terra, --sans, --bg, --ink-muted, ...) are
   kept as aliases so no page loses its colors.

   2026-06-03: brand updated to the "barn / farmhouse" palette
   (barn-brick accent, bone paper, warm dark sections) with
   Crete Round + IBM Plex Sans/Mono type.
