/*
 * skin.css — P08 Service Kit commerce skin (component SK-B; owner SK-B-P08-skin-builder).
 * Overrides commerce/base/flow.css. Tokens and geometry from samples/08-service-kit/styles.css
 * (:root lines 1–17: paper canvas, 2 px ink rules, 9 px offset shadow, pastel module tints, Arial).
 * Light scheme only (concept page is color-scheme: light). Pastel tints are category cues that are
 * always paired with the visible "Category" text in each module — never the sole cue.
 * No cart / package semantics; the product "spine" bar is pure CSS decoration.
