+ * One product on a logged-in user's wishlist. A guest's wishlist lives in a
+ * cookie instead (see Modules\Core\Wishlist\Services\Wishlist) — nothing is
+ * written here until Modules\Core\Wishlist\Listeners\MergeGuestWishlistOnLogin
+ * moves the cookie's ids across on login.
+ *
+ * hasTable() guard: this table previously lived in each consuming app's own
+ * migrations (e.g. 3dealer's create_wishlist_items_table, extracted here) —
+ * Laravel's migrations table tracks by filename, so a consumer that already
+ * ran its own copy would otherwise hit "table already exists" the first time
+ * this migration runs. Skips creation entirely if the table is already
+ * there; a fresh install with no prior wishlist table gets it created here.
