Returns preset degraded to the given adaptation level (0 = unchanged). Levels
coarsen the LOD selection (lodRenderScale — Spark documents values up to ~5 as often
indistinguishable), shrink the LOD splat budget (lodSplatScale) and, at higher
levels, tighten the overdraw caps. Pure — does not touch any renderer.
