* feat(studio): timeline lane-zone model What: new pure module timelineZones — visual/audio track-zone classification (classifyZone) and normalizeToZones, which re-packs lanes into zone-consistent rows; tests cover the stacking/zones interaction. Why: completes the z-model started in the stacking-sync PR. How: new files; consumes isAudioTimelineElement (leaf-helpers PR) and computeStackingPatches (stacking-sync PR); type-only playerStore imports. Test plan: bunx vitest run timelineZones.test.ts; tsc --noEmit; fallow audit clean. * feat(studio): asset click policy and canvas nudge gate What: two small pure modules with tests — assetClickBehavior (click vs double-click policy for sidebar assets) and canvasNudgeGate (debounce gate for arrow-key canvas nudges). Why: policy dependencies of the upcoming asset card and nudge hook, reviewable as plain decision tables. How: new files only. Test plan: bunx vitest run on both test files; tsc --noEmit; fallow audit clean.
