Get the coffee shop's current menu: every drink we can make, whether it contains milk, and a short description. Call this FIRST to see what the customer can order. Do not guess drinks or read source files.

Get the available customization options for a specific drink (size, extra shot, etc.). Call this after the customer has chosen a drink from the menu, so you know what to ask them about. The drink argument must be a drink name from the menu.

Place a coffee order. Call this once the customer has chosen a drink and confirmed their customizations. Returns an order ID and the recipe (the ordered list of machine steps to make the drink). drink must be on the menu; size is small/medium/large; extra_shot adds a second shot.

Update the current machine step for an in-progress order. Call this as you BEGIN each step in the recipe: 'grinding', 'brewing', 'steaming' (milk drinks only), 'dispensing'. Do NOT use this for 'pending' (set by place_order) or 'ready' (set by mark_order_ready). Calling 'steaming' on a non-milk drink is a validation error.

Check the current status of a placed order by its order ID. Returns the drink, size, current status, the full step-by-step status history with timestamps, and when it was placed. Use this to tell the customer whether their order is still being made or is ready.

Mark an order as ready for collection. Call this after ALL machine steps in the recipe have been completed successfully. Flips status to 'ready', records the completion timestamp, and closes the lifecycle. After calling this, tell the customer their order is ready to collect.
