## Problem Studio manual drag had two bad target paths in `hf-keyframes-test`: - Drag could start from a cached hover selection instead of the selected overlay, so moving `#cta` could write an offset to the wrong element while the overlay appeared correct. - `#stage` is the visual 1920x1080 canvas, but the composition metadata lives on `<html data-composition-id ...>`. Studio treated `#stage` as a normal movable layer, so dragging it moved the coordinate basis the overlay depends on and left Undo with no reliable saved edit to reverse. ## Fix - Manual drag now starts only from the selected overlay bounds; canvas pointer-down no longer starts movement from `hoverSelectionRef`. - Added a structural root-layer heuristic: a direct body child matching the composition root's declared `data-width` / `data-height` is selectable and style-editable, but cannot receive manual offset/size/rotation edits. - Manual geometry commits now return/rethrow the save promise so failed writes roll back optimistic DOM changes instead of silently sticking. - GSAP-targeted CSS fallback edits are blocked before applying manual geometry when the GSAP drag intercept is unavailable. ## Tests - New regression coverage for stale-hover drag start and full-canvas root-stage capability resolution. - Focused DOM-edit suite: 119/119 pass. - Full Studio suite: 800 pass, 18 todo. - Studio typecheck clean; oxlint/oxfmt clean; lefthook pre-commit clean. - Studio build passes with the existing Vite chunk-size warning. - Browser verified with `agent-browser`: attempted `#stage` drag writes no offset and keeps Undo disabled; `#cta` drag writes exactly one offset to `#cta`; Undo returns the fixture to zero offsets.
