Build a birthday party planner app as one HTML file that works on a phone or desktop and saves on the device.

Birthday person: (not given) (if not given, use "the birthday kid"), turning (not given) (if not given, leave age out).
Expected guests: 10-20. Budget range: 150-400 (pick a starting total in that range, editable).

What it does:
- A header with the party date, time and place (editable) and a countdown in days.
- Guests: add name, number of people and RSVP (yes, no, maybe); totals of who is coming.
- Tasks: a checklist with due dates and sorted by date (for example book venue, order cake, send invites); overdue tasks are marked.
- Budget: line items with planned and actual cost, total spent, total left, and a bar that turns a warning color when over budget.
- Prefilled with a sample guest list, tasks and budget lines so it looks alive on first open.
- Delete with undo, print view, and export and import all data as a file.
