/* ============================================================================
   Brick Auction — shop page (/products) — «چک»
   Loaded ONLY by products.html, on top of styles.css: the chrome (.nav, .btn,
   .chip, .section-head, .footer, the reveal animation) is reused as-is and
   every colour here comes from the same "Warm Monochrome" tokens, so nothing
   in index.html's payload changes.

   The page is a catalogue + a purely client-side cart. There is no checkout
   here by design — the CTA hands the visitor to the customer app.
