/* =============================================================
   NOD — shared blind storefront header (store home + by-size
   landing pages + the order builder). Matches store.html's header:
   brand (logo or name) → store home, product nav, "Start an order"
   CTA. Colors key off the --brand family (set per-store by
   store-theme.js) with neutral fallbacks so it's never unstyled.
   Rendered by store-header.js into <header data-store-header>.
