// Restaurants seed — a BUILD-TIME script, never shipped in the app. Run from the project
// root (where wix.config.json lives) with a plan file:
//
//   node <SKILL_ROOT>/references/restaurants/seed/seed-restaurants.mjs plan.json
//
// It mints its own site token via the Wix CLI, installs the Wix Restaurants Menus app (plus
// Orders / Table Reservations when the plan asks), builds each menu BOTTOM-UP (bulk items →
// bulk sections → menu — every child exists before its parent, visible:true at every level),
// imports+attaches item images, and configures the add-ons. Prints a JSON result to stdout.
//
// Plan shape (see SEED.md):
//   { "menus": [{ "name", "description"?, "sections": [{ "name", "description"?,
//                 "items": [{ "name", "description"?, "price", "imageUrl"? | "imagePrompt"? }] }] }],
//     "ordering"?: true | { "address"? },        // menu-first add-on; address is STEP 0
//     "reservations"?: true | { "partySize"? { "min","max" }, "address"? } }
//
// Seeding is ADDITIVE — with ONE recipe-sanctioned exception: when THIS run installs the
// Menus app onto a site that didn't have it, the install's own sample "Dinner Menu" is
// removed (it's provably not owner content). Nothing else is ever deleted. Unexpected
// shapes → read the live API reference; authoritative source recipes:
