   OpenGauntlet — static leaderboard styles.
   Design direction: a measurement instrument for warmth in machines.
   Two voices: MONO is the DATA voice (labels, numbers, headers, eyebrows, badges,
   axis ticks); SANS is the PROSE voice (headlines, dialogue, methodology copy).
   The signature element is the Warmth Verdict Strip — a vertical thermal rail
   plotting each model on the normalized-Elo axis. Dark, self-contained, no CDNs.
