Mob level per wave — the biome×wave formula

A single function level(biome, wave) that reproduces Claw Master's per-wave enemy level for biomes 1–16 and extrapolates beyond — for auto-generating new biomes with CM-approximate balance. This is the input to Enemy Progression, which turns the level into HP/DMG.

Accuracy vs Claw Master (all 200 waves, biomes 1–16)

Boss (last-wave) levels reproduced within ±1% for every biome. Worst single cell (28.6%) is an early onboarding wave in Biome 1 where the true level is single-digit — a 1–2 level miss reads large in % but is trivial in play.
