• Implemented invisible subtitle position edit mode toggle with movement/save/cancel controls.
• Added persistence for invisible subtitle offsets (invisibleOffsetXPx, invisibleOffsetYPx) alongside existing yPercent subtitle position state.
• Updated edit mode visuals to highlight invisible subtitle text using the same styling as debug visualization.
• Removed the edit-mode dashed bounding box.
• Updated top HUD instruction text to reference arrow keys only (while keeping hjkl movement support).
