device.py's mode-keyed dispatch is replaced by a real compositor: load a frame's widgets, compute pixel rects via app/grid.py, render each through its widget module, and composite with render_panel. Physical NEXT/BACK buttons now execute each frame's assigned FrameButtonAction rows instead of one hardcoded per-mode action. api_frames.py, manage.py, and common.py's build_manage_content are repointed to read/write the frame's widget config rows instead of the old Frame columns, and every settings page (Photos/Calendar/ Whiteboard tabs) now pre-fills its form from the same widget config the write endpoints actually save to -- previously the read and write sides would have silently diverged. The old mode selector and photo-inlay checkbox are removed along with their now-inert wiring; arbitrary widget placement subsumes what the fixed inlay split did. Ships together with Phase 1 (per-type render/action modules) since splitting the read/write cutover across deploys would have left settings changes with no visible effect.
