/**
 * Breatheazy Product Page Enhanced Styles
 *
 * Additional product page styles for issue #8:
 *   - Gallery enhancements
 *   - Mobile-first layout (Image > Price > CTA > Details)
 *   - Touch-friendly buttons (44px minimum)
 *   - Sticky mobile Add to Cart bar
 *   - Social proof / testimonials section
 *   - Section headings
 *
 * Works alongside product-page.css (issue #7) without overriding it.
 * Uses CSS custom properties (--breatheazy-*) with hardcoded fallback values.
 * The :root definitions for these properties should be added in the child
 * theme's style.css (tracked in issue #5 / PR #31). Until then, the fallback
 * values ensure correct rendering.
 *
 * @package Breatheazy_Child
 * @since   1.0.0
