/* ==========================================================================
   Instagram Shoppable Feed — storefront

   Styled to sit with the NopNoor theme's own home page sections: the same
   centred 30px Manrope titles, the theme's gold (--primary) as the only accent,
   near-square corners like the product cards, and the theme's text colour.

   Mobile first. The rail scrolls natively so a finger drag needs no JavaScript,
   and the viewer is a single column on phones: media on top, the products
   mapped to that post underneath.
