Audio Lanes: Features waveform visualization, J-cut/L-cut support, keyframe volume levels, and fades.
Overlay Track: Supports alpha channels for transparent PNGs (logos, lower thirds) and automatically keys out black backgrounds common in AI-generated images.
Pro Export: Exports to Premiere/Resolve/After Effects project folders with media relinking and separate audio stems.
Storyboard Continuity: Introduces floor plan mapping for consistent lighting/positioning and dialogue duration measurement to prevent mid-sentence cutoffs.

Fixes: Resolved black frame flashes, transparency flattening, and preview/render mix discrepancies.
