Open Festival Planner

A deterministic itinerary planner for the Big Three European film festivals — Berlinale, Cannes, and Venice. Pick your dates, pass, and preferences; it solves the access-rule, transfer-time, and daily-limit constraints and returns a validated, conflict-free schedule with a reason for every rejection. Runs entirely in the browser (English / 中文), no server. The Python reference implementation and its JavaScript port are kept byte-identical by a seeded parity fuzzer in CI. Films meet algorithms.
