   SYHF 2026 — Competitions (competitions.html)

   Brief was explicit: not bland, not white, as vivid as the Stage and Surgical
   pages. Both competitions are on screen from the first frame — the complaint
   about the rest of the site was having to scroll to discover the options.

   Two colour identities, both from locked tokens: the Olympiad reads as the
   quiz arena (mint/green), MEDATHON as the build arena (violet/sky).
