/* ============================================================
   Hajime - public surface (home + tournament page). Spec 037/038.
   Adapted from the claude/design concept: warm-charcoal + gold +
   Inter / IBM Plex Mono, light/dark tokens. The review chrome
   (concept bar, device frame, tweaks dock) and the unused variants
   (asymmetric hero + live panel, stacked tournament card) are dropped
   per the fixed design decisions; the page renders the centered hero
   and the row tournament card. Responsive via container queries on the
   .product container, so it reflows on real viewports.
