   HIGH-1: Enforce square aspect-ratio on product thumbnails

   ~70% of thumbnails are 1000×1000. The rest are 1000×(877–999).
   Without a fixed ratio, rows have uneven tile heights.
   aspect-ratio: 1/1 + object-fit: cover crops the few non-square
   images by at most ~12% off the bottom — acceptable since the
   subject is always centered.

   Replaces: .product.type-product img (my_custom_css.css:2779-2790)
   ========================================================== */
.product-grid-section .product.type-product img {
    aspect-ratio: 1 / 1;
    width: 100%;
    height: auto;
    object-fit: cover;
    display: block;
    margin: 0 auto;
}

/* ==========================================================
   HIGH-2: Consistent tile sizing via .product-item rules

   Previously had ZERO CSS rules. Tiles relied entirely on
   content size, causing inconsistent heights within rows.
   display: flex + flex-direction: column lets the image fill
   available space while the title stays at the bottom.

   Adds rules for: .product-item (functions.php col wrapper)
   ========================================================== */
.product-grid-section .product-item {
    display: flex;
}

.product-grid-section .product-item > li.product {
    display: flex;
    flex-direction: column;
    width: 100%;

   MED-4: Remove min-height: 100vh on product grid sections

   .section-py forces min-height: 100vh globally. This creates
   large empty gaps below product grids that have fewer products.
   Override for product-grid-section only — other sections that
   use section-py are unaffected.

/* ==========================================================
   MED-5: Line-clamp product titles to 2 lines max

   Without a clamp, long product names wrap to 3+ lines and
   create uneven tile heights within the same row. 2 lines
   accommodates most names; longer ones get ellipsis.

              (my_custom_css.css:2768-2775)

/* ==========================================================
   MED-6: Row-gap for consistent vertical spacing

   display_category_products() outputs plain .row divs with
   no row-gap. The only vertical spacing was mb-4 on each tile.
   Adding row-gap on .carousel-item gives consistent spacing
   between the two rows of tiles.

   LOW-9: Carousel arrow sizing and spacing

   Bootstrap default icons are 2rem (32px). The arrows sit

   via d-flex justify-content-end. Current CSS only sets
   width: auto — no explicit sizing or hover feedback.
