/**
 * Location: /assets/css/main.css
 * Purpose:
 * - Global base styles + Woo global grid + shared UI styling.
 * - IMPORTANT: Header system styles are NOT defined here to avoid conflicts.
 *   Header UI is handled only in: /assets/css/header.css
 *
 * Related CSS:
 *  - /assets/css/header.css (header system; enqueued by /inc/features/header/header.php)
 *  - /assets/css/sidebar.css (sidebar grid system; conditionally enqueued)
 *  - /assets/css/blog.css (blog loop/grid/card system; conditionally enqueued)
 *  - /assets/css/stm-woo-sidebar-balance.css (Woo container width; conditionally enqueued)
 *  - /assets/css/single-product-layout.css (single product layout module; enqueued only on is_product())
 *
 * Notes (THIS UPDATE):
 * - Performance-first: keep main.css render cost low.
 * - Adds safe below-the-fold rendering optimization using content-visibility where it does not break interactive overflow.
 * - Blog loop/grid rendering is intentionally excluded from content-visibility because hover lift/shadow must remain unclipped.
 * - Blog loop/grid styling is intentionally not defined here; it lives in /assets/css/blog.css to avoid conflicts.
