/* Header, footer, floating dock, mobile tab bar, and shared page grid.

   The header is three stacked strips, as in the storefront design:
     1. utility strip  - deep pink, trust + hotline, desktop only
     2. main strip     - brand pink, logo / search / account / cart
     3. category strip - white, one row of category links
   Colour does the layering work, so the three strips need no borders. */
