// Looks — curated one-click bundles of the CRT/effect knobs. Picking a Look sets
// every effect slider (and a matching color) at once, so users get a coherent
// vibe without tuning ~10 controls. Scene + terminal size stay user-controlled.
// Pure data → lives in Core (shared, testable). The config window applies these.
