   S3 ATHLETIC PERFORMANCE — DESIGN TOKENS
   Palette: ink black / charcoal / gold gradient / bone / track red
   Type: Oswald (display, scoreboard energy) + Inter (body) + JetBrains Mono (data)
   Signature: timing-gate brackets ⟦ ⟧ used as the structural motif
              throughout, echoing the FreeLap photocell gates S3
              actually trains with — not a decorative numeral system.
