/* ===========================================================================
   HOMESARA THEME — page-product-mattress.css
   Layers on top of page-product-normal.css (see inc/enqueue.php) — like
   page-product-fabric.css, this is NOT a copy of legacy/product-mattress.css
   (behavior-spec mockup only, plan §5). This is the real delta: the
   Select Size / Thickness row and the WhatsApp CTA box, rebuilt as proper
   classes from the exact inline-style values the mockup specified.

   The Select Size / Thickness buttons themselves reuse .btn.btn-outline
   from the root style.css — only the wrapping row and the CTA box are new.

   Choose Size — combined size + thickness picker in ONE control, per the
   reference screenshots: one trigger, one modal with bed-type tabs
   (Single/Queen/King/Custom, derived from width - see
   homesara_bedtype_for_width()), a dimension grid, a thickness row, and
   Confirm/Cancel. Uses the site's own brown/gold tokens (not a separate
   colour scheme) since the reference design itself uses them.
