   LAYOUT FIX — GeneratePress flex container on category pages.

   GeneratePress sets .site-content { display: flex } for its sidebar/
   content layout. By default flex-wrap is "nowrap", which forces ALL
   direct children onto one horizontal line — that is why the tabs and
   products sit side-by-side instead of stacking vertically.

   Two things must work together:

   Step 1) Allow the flex container to wrap onto multiple rows.
   Scoped to .tax-product_cat so this only affects WooCommerce product
   category archives and never touches other pages on the site.

   Step 2) Give .subcategory-tabs-wrapper flex: 0 0 100% so it claims
   the full first row. Once the parent allows wrapping, this forces
   .content-area onto the second row below the tabs.
   ------------------------------------------------------------------------- */

/* Step 1 — allow GeneratePress site-content to wrap on category pages only. */
.tax-product_cat .site-content {
    flex-wrap: wrap;
}

/* Step 2 — make the wrapper claim its own full-width row. */
.subcategory-tabs-wrapper {
    position: relative;     /* anchors the absolutely-positioned nav arrows */
    display: block;
    width: 100%;
    flex: 0 0 100%;         /* claim the entire first flex row */
    align-self: flex-start; /* do not stretch vertically to match siblings */
    min-width: 0;           /* prevents overflow in some flex implementations */
    clear: both;            /* float-layout fallback for older theme variations */
