/* Orbace Sudoku — consolidated game card (docs/plans/2026-07-15-consolidated-game-card-design.md).
 * Namespaced under .osgc- (Orbace Sudoku Game Card). Wraps whatever a call site
 * mounts inside it (.og-wrap / .osr-layout / the legacy Play-page .board-wrap)
 * with a shared bordered shell, a metadata header, and a brand slot. Retires
 * the one-off .v1-home-theater (css/styles.css).
