/* Digital Scrapbook (architecture.md §50, Design.md §12).
   ---------------------------------------------------------------------------
   Register: the HOMEY one — the same family as the Couples Hub (washi tape,
   handwriting, things sitting a little crooked), not the cool photo-paper white of
   the booth. So this is the one surface in the app that is deliberately WARM.

   PAPER IS CSS, NEVER AN IMAGE. A scrapbook's whole surface is paper; an asset per
   sheet would be the heaviest thing we ship for the least reason. Every sheet below
   is gradients only — which also means a page renders instantly and prints nothing.

   Our classes are all `sb-*`. `.ed-ink*` and `.ed-ring` belong to the Print Studio's
   ink component (studio/editor/ink.js), which the book scene reuses wholesale — they
   are styled here because we don't load studio.css. */
