/* Glyph One — v0
 *
 * Aesthetic: the single letter as a poster. Near-white ground (#F4F2EE,
 * Avi's brief). One typeface per round, set at 720pt. Chrome is small,
 * quiet, and out of the way. The reveal page is the artifact; everything
 * else is staging.
 *
 * Layout rule: the stage occupies the visual center. The chrome lives
 * above (puzzle no.) and below (the chips, or the craft note). The
 * stage's intrinsic size scales with viewport — at desktop the glyph
 * renders at the literal 720pt the brief specifies; on smaller viewports
 * it scales down with `clamp()` but never below ~32vh.
