 * laptop that reads as a mockup of a phone app, not the app ("stop making the
 * iphone apps embedded pages with weird ui hanging off them like a title
 * twice", SING BACK, 2026-09-12). So the stage IS the window now: full height,
 * no border, no shadow, no radius, the ground painted on the body, the name
 * said once.
 *
 * What the fixed box bought — the same rectangle for every player — is a
 * property of the PLAY SURFACE, not of the page. Content sits in a column
 * (--play-max) so a board is the same shape on a phone and a laptop, and a
 * game that genuinely needs the old identical box sets `stage: "fixed"` in
 * relay.config.mjs. */
