/* ── Mobile section reorder (checkpoint 1 of N) ──────────────────────────────
   Goal: let Product Details/FAQ (rendered by the theme's product-image.php,
   nested inside .woocommerce-product-gallery) become independently
   repositionable via CSS `order`, without moving the PHP template call —
   moving that call broke desktop once already (2026-08-03) since the theme
   file has no viewport gating of its own.
   `display: contents` makes .woocommerce-product-gallery itself disappear
   from layout on mobile, promoting its children (#b2b-gallery the design
   tool, and .b2b-left-accordions the Product Details/FAQ block) to be
   direct flex items of .product-details-wrapper (the theme-injected shared
   parent of the gallery and .summary column) instead. This is a NECESSARY
   BUT NOT SUFFICIENT step toward the full interleaved mobile order — true
   interleaving between Colors&Sizes and Add Decoration additionally
   requires restructuring #b2b-order's internal step rendering (deferred,
   separately-scoped follow-up work). This checkpoint only makes Product
   Details/FAQ and the gallery block independently orderable relative to
   each other and to the summary column as a whole. */
