   v15 — MOBILE LAYOUT FIX  [2026-05-18]

   Problem: On mobile, .pc-section (24px) + nested .pc-container (24px)
   were stacking → 48px horizontal padding per side, eating ~25% of a
   380px viewport. Combined with any 1–2px horizontal overflow from
   floating widgets (cart badge, drawer overlay, box-shadows), the
   browser would expose a horizontal scroll and the page felt visually
   pushed to the right.

   Fix:
   1. overflow-x: hidden on html/body kills any accidental h-scroll.
   2. On ≤600px, .pc-container becomes a passthrough (padding:0),
      so .pc-section alone controls horizontal indent (14px).
   3. Force single-column grid + tighter gap so cards breathe properly.
   4. Tighter hero/filters padding to match.
   =================================================================== */

/* Hard guard against any horizontal scroll caused by fixed/sticky widgets */

  overflow-x: hidden;
  max-width: 100%;
}

@media (max-width: 600px) {
  /* Hero — generous vertical, tighter horizontal */
  .pc-hero {
    padding: 44px 16px 40px;
  }

  /* Don't double up padding on mobile — container becomes passthrough.
     .pc-section alone now owns the horizontal indent. */
  .pc-section {
    padding: 0 14px 48px;

  /* Card grid — one column, tighter gap */

  /* Filters bar — keep readable, less padding */
  .pc-filters {
