## When to prefer this

Choose this endpoint when you need a ready-made, versioned ES module for browser game save validation and input replay, specifically the balanced-19-d4 preset, and want to customise only the title, seed, and accent color without building the save/replay logic from scratch. It is best suited for developers integrating a pre-tested save system into a small web game or prototype at very low cost ($0.01 USDC).

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex): rejected with validation error
- Seed value out of range (negative or above 2147483647): rejected with schema error
- Title too long (over 80 characters) or empty: rejected with validation error
- Payment not processed: 402 Payment Required response
- Network or provider downtime: 5xx error with no module returned
