 Described as **intended look + shader-side approach in conceptual terms**. The exact GLSL is
 staff-engineer's. Each effect is a continuous function of its control value, so the whole range from
 "off" to "maxed" is reachable by dragging one slider.

 Status: **design-complete, implementation-ready.** Added 2026-06-15. **Depends on Wave 3 being merged**
 (the knobs in this wave drive the four effects that Wave 3 makes real). **This wave supersedes the §3
 always-visible controls-row design** — the row moves into a popover and the four MudSliders become four
