Tuning notes: the first pass (80px tile, 3 rings, 0.14 opacity) looked fine
in an isolated mockup but was overwhelming across a full page — this
120px/2-ring/0.06-opacity version is the one that actually reads as quiet
atmosphere at real page scale. Verify any future change against a full
rendered page, not a small swatch.
