   Win-moment share component — scoped "pcshare-" classes ONLY.
   Reads the design tokens from styles.css (plus a few component-scoped chip
   tokens defined on .pcshare-row itself), so dark mode + reduced-motion come
   for free. NOT a popup/banner: a quiet caption + one filled primary and three
   always-visible channel affordances, shown only AFTER the download succeeded.

/* ── Component-scoped colour tokens ──────────────────────────────────────────
   The chips need a surface DISTINCT from the row they sit in. In light the row
   is --surface-2 (#fafafa) so the chip goes white; in dark the row is #1c1c1f so
   the chip must step UP to #26262b (using --surface #141416 would make the chip
   darker than its own container — backwards elevation). Same raised-dark-surface
   value as the ownAd card precedent. */
