   @shard S11
   Trail Run skin pack -- Oaks variant. Pitch-stadium palette, electric-mint
   accent, halftone ambient. Fixes the prior build's missing/wrong
   --runner-sprite-url URL (SOLUTION sec.3 -- folded into S11).
   The existing /shared/trail-run/ engine reads these tokens via the
   trail-run-skin contract (no engine changes this build).
   ZERO JavaScript in this shard (NO-JS LOCK). */
