// ─── WooCommerce feature compatibility ──────────────────────────────────────
//
// WooCommerce shows an admin notice ("some of your active plugins are
// incompatible with currently enabled WooCommerce features") for any
// active plugin that touches orders/products but hasn't explicitly told
// WooCommerce whether it works with newer features — High-Performance
// Order Storage (HPOS / "custom order tables") chief among them. This
// plugin never reads/writes order data via raw wp_posts/wp_postmeta
// calls (order state lives in its own qbws_order_map table, and every
// order field is read/written through wc_get_order()'s own meta API —
// see class-qb-sync-orders-outbound.php for why that matters), so it's
// genuinely safe to declare compatibility rather than just silencing the
// warning.
//
// Cart/Checkout Blocks compatibility isn't declared here — this plugin
// doesn't render or modify checkout UI at all, so that feature is simply
// not applicable to it either way.
