/*
 * SCRATCH - visual system.
 *
 * Letterpress rules, applied without exception:
 *   borders  3px solid var(--ink)
 *   shadows  6px 6px 0 var(--ink), never blurred
 *   corners  square, border-radius: 0 everywhere
 *   colour   flat fills only, no blends
 *
 * The foil hatching below is a repeating pattern built from hard colour stops,
 * so it prints as ruled lines rather than a blend. There is no soft gradient
 * anywhere in this file, and no external asset: a strict CSP is coming in
 * phase 6 and this stylesheet must not need an exception.
