Choose this endpoint when you need a ready-made, versioned ES module for browser game localStorage save validation and input replay, and you want to start from a known preset (open-27-d4) rather than building from scratch. Ideal for game developers who need reproducible replay logic with minimal setup and a configurable theme.

## Known failure modes

- Invalid accent color format (must match ^#[0-9a-fA-F]{6}$) returns validation error
- Seed out of range (must be 0–2147483647) returns validation error
- Title exceeding 80 characters or empty string returns validation error
