/**
 * nak-flow.css — Culture Flow design layer (1.13.0)
 *
 * The three culture icons — Ganesha (Indian), Apsara (Khmer), Atom (Fusion) —
 * drawn into the design, plus each culture's own front page:
 *
 *   - --nak-motif per style → brand mark, section eyebrows, storefront
 *     medallions all carry the culture icon (CSS mask, takes currentColor).
 *   - Header style rail → icon + label; links to each culture's front page.
 *   - "Three kitchens, one table" → a card per culture, each in its own palette.
 *   - Footer "Our Kitchens".
 *
 * Loads after nak-foh.css. Token-driven: everything re-skins with
 * <html data-style="indian|khmer|fusion">.
 *
 * @package NamasteAngkorTheme
