/*
 * Shared product-templates stylesheet.
 *
 * Used by BOTH templates (4.7.21+):
 *   - tpl-product-collection-v3.php  (v3 catalog hub)
 *   - tpl-product-detail.php          (pd single-series hub)
 *
 * Both templates intentionally share 100% of the visual language —
 * card style, FAQ, hero layout, why-card, support cards, etc. — so all
 * rules live in this single file. Keeps:
 *   ✓ One source of truth (fix once, both templates updated)
 *   ✓ Zero rule duplication
 *   ✓ One HTTP request per page (~5KB gzipped)
 *
 * Section layout in this file:
 *   1-13   v3 + pd shared components (cards, hero, FAQ, related, support…)
 *   720+   pd-only additions (.hs-pd-hero-gallery / .hs-pd-tabs /
 *          .hs-pd-byline). Even these load on v3 pages (~1KB extra) but
 *          are harmless — selectors don't match v3 markup.
 *
 * Site-wide primitives (.hs-container / .hs-section / .hs-section--alt /
 * .hs-btn / .hs-grid / .hs-eyebrow / .hs-section-head) come from site.css.
 *
 * File name kept as "product-collection-v3.css" for backward compat with
 * external SOPs / build scripts. If you ever decide to rename, also update
 * inc/theme-settings.php and inc/product-detail.php enqueue paths.
