/* Vitamex V4 — PDP template styles (v1.1.0).
 *
 * Replaces the v1.0.x draft, which styled WooCommerce's default markup.
 * This file styles the gated V4 single-product template
 * (templates/single-product.php) only. Every rule is scoped under .vx4 and
 * every class is pdp- prefixed, so nothing here can leak into the theme's
 * pages, and on live (non-gated) product pages, where no .vx4 wrapper
 * exists, the file has no visual effect. Palette variables (--deep, --cta,
 * --sun, --line, ...) come from assets/css/vx4.css, which the gated PDP
 * enqueues first. Selectors are written complete on single lines — the
 * dangling ".vx4 /* name" fragment pattern from vx4.css is NOT used here
 * (it caused the v1.0.1/v1.0.3 selector bugs). All grid tracks are
 * minmax(0,...) and grid children carry min-width:0, per the v1.0.3
 * 390px-overflow lessons. */
