/*
 * ════════════════════════════════════════════════════════════
 *  PRODUCT DETAIL PAGE — LAYOUT FIX
 *  File: assets/css/product-fix.css
 *  Include AFTER main.css in header.php
 *  Pure CSS override — zero PHP / JS changes.
 * ════════════════════════════════════════════════════════════
 *
 *  PROBLEMS FIXED
 *  1. .pd-layout used hard minmax() floors (300 + 360 = 660 min)
 *     → overflowed on 700-1100 px viewports.
 *  2. 14 thumbnails in a single non-wrapping flex row
 *     → scrolled / overflowed outside the card.
 *  3. object-fit: cover distorted tall product images.
 *  4. align-items: start caused mismatched column heights.
 *  5. .pd-info-panel gap:12px created uneven internal spacing.
 *  6. No responsive rules between 768-1200 px for product page.
 *  7. Mobile stacking lacked max-width / centering for gallery.
 * ════════════════════════════════════════════════════════════
