/* Phase 6c: quick-add modal. Loads after ww-shop.css (design tokens), on
   every WooCommerce page (shop/category/tag archives + single-product,
   since the `product-card` template part with the quick-add button also
   appears in the PDP's "Related products" block). No !important anywhere —
   selectors are written specific enough to win the cascade on their own,
   same approach as every other Phase's CSS in this plugin.

   The modal reuses the REAL woocommerce/add-to-cart-with-options block
   markup (fetched from the Phase 6c REST endpoint — see
   waifuworld_render_add_to_cart_with_options_form() in the main plugin
   file), so its button/quantity-stepper/variant-pill styling below mirrors
   the PDP's "plain/restrained" look (ww-shop-pdp.css) rather than
   duplicating it — that PDP stylesheet is scoped to `.single-product` body
   class and wouldn't apply inside the modal on a shop/category page. */
