File path

/app/output/itinerary.json

Top-level structure

{
  "plan": [ /* array of exactly 7 day objects */ ],
  "data_sources": [ /* list of dataset files used */ ]
}

Day object fields

Field	Type	Notes
`day`	integer	1–7
`current_city`	string	City name, OR `"from A to B"` when traveling
`transportation`	string	`"Self-driving: from A to B"` — no flights

Rules

Use "-" for meals intentionally skipped (e.g., long driving days).
transportation is "-" when staying in same city.
Attractions end with ; even if only one.
accommodation is "-" on final day if returning home.
Restaurant format: "Name, City" (matches CSV Name and City columns).
