INSTRUCTIONS FOR AI AGENTS — Rootline Cafe cart prefill

WHAT THIS DOES
You can hand a customer a single URL that opens Rootline Cafe's checkout
page with their order already filled in. The customer then taps to pay
themselves. You CANNOT place the order or complete the payment for them.

URL TEMPLATE
https://rootline.cafe/checkout?items=<id>:<quantity>,<id>:<quantity>,...

HOW TO BUILD THE URL
1. Pick one or more item ids from the MENU section below.
2. For each item, append "<id>:<quantity>". Separate items with commas.
   The quantity is optional; if you omit it the default is 1.
3. Send the resulting URL to the customer to open in their browser.

EXAMPLES
  Customer wants 2 espressos and 1 croissant:
    https://rootline.cafe/checkout?items=espresso:2,croissant:1

  Customer wants 1 americano and 1 croissant (quantities omitted, both default to 1):
    https://rootline.cafe/checkout?items=americano,croissant

RULES
- <id> MUST match exactly one of the ids in the MENU below (case-sensitive).
- <quantity> must be an integer from 1 to 99. Values above 99 are clamped.
- Unknown ids and non-positive quantities are silently dropped.
- Whitespace around tokens is ignored.
- If the same id appears more than once, the quantities are summed.
- Prices are in EUR. The customer can add a tip on the checkout page.
