use FluentCart\App\Listeners\UpdateDefaultVariation;

/**
 * Fired when a product's variation set changes in a way that can invalidate its
 * default_variation_id — combinations regenerated/removed, or a variant set
 * active/inactive. Distinct from StockChanged (which is broad and currently
 * carries no default listener) so this stays scoped to variant-set mutations.
 * UpdateDefaultVariation re-resolves the default to the first purchasable
 * combination; works for every variation type.
