/* One Page Toys — shared toy chrome, direction B "tinted by the toy" (owner, 2026-10-24).
 *
 * One structure for the furniture every toy repeats (the start/end card, its button, eyebrow, body
 * and hint line, the score bar), coloured by each toy's own accent. A toy opts in with
 * <html class="tc"> and this sheet loaded AFTER its own styles.css, and sets its look with a few
 * variables in its own :root:
 *   --tc-accent   the toy's signature colour (button fill, eyebrow, tint)       required
 *   --tc-on       text on the button (dark on a light accent, white on a dark)  default #0b0b0e
 *   --tc-display  the title face (keeps the toy's own display font)             default inherit
 *   --tc-ground   the dark the card is tinted from                              default #0a0b0e
 * Everything else stays the toy's own: its world, its canvas, its icon buttons.
 *
 * ⚠ Self-contained on purpose: no url() and no @import. The iPhone app copies this file on its own,
 *   and anything it points at in assets/ would not exist there. Fonts come from the toy's own import
 *   (add Geist to it) or the app's bundle; the stacks below fall back to the system face.
