/*
 * THE SHARED-COLLECTION VIEWER — one stylesheet, the app's own numbers.
 *
 * Day tokens are the app's MINERAL palette (src/theme/afterimage.ts); the
 * media viewer keeps the app's black stage and its glass discs. Radii are the
 * app's `rad` set, easings its `am` set. The page is a phone column: one
 * reading width, centred on anything wider, with the same canvas underneath.
