 * Optical contract for the Meta Ray-Ban Display waveguide:
 *   - the only opaque background anywhere is #000000 (black is transparent on
 *     the waveguide); everything else is outlined, never filled;
 *   - a 24 px safe margin on all four sides, applied once on .canvas;
 *   - no font below 22 px (--fs-small);
 *   - the only motion is a 200 ms opacity crossfade when the channel changes.
 * Shared by index.html (glasses), remote.html (phone) and pair.html.
