/**
|
||
* Level system — 100 levels per game, deterministic seeds, graduated difficulty.
|
||
*
|
||
* Seed strategy: level N → synthetic date "LEVEL-{game}-{N:03d}"
|
||
* Each generator uses date.split("-").reduce(…) to derive a numeric seed,
|
||
* so we pass a date-shaped string that yields a unique seed per (game, level).
|
||
*
|
||
* Level N → date string: `${1900 + N}-01-01`
|
||
* This stays far from real daily dates (2024+) and is unique per level.
