/* Trauma at the Tree — SAC Youths, 27-29 Aug 2026
   Palette sampled programmatically from web/public/assets/poster.jpg (see
   docs/ARCHITECTURE.md, "Branding"), not hand-transcribed. Dark-only by
   design: the audience is phone-first in a dark auditorium (handoff §6) —
   no light theme, no toggle, to keep scope down to what was actually asked
   for. Tokens are still named generically so a future SAC Youths event can
   swap values here without touching markup or JS. */
