Keeps both lines: master's PGXP session, draw-distance clamps, masked rejects and saturated-winding NCLIP; the release's render-pass kit additions, verified media/disc extents, timeline/present rings, cull-scale sites. Overlay ABI v30. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
