Round 14 — True two-material morph. The sphere transformation now uses only the original visible sphere material: light sphere surfaces converge into one white product surface and dark sphere surfaces converge into one black product surface. No bridge, product overlay, sphere energy ring, separate Support tail layer, or separate Notes fold layer is introduced during the morph. The Support tail is part of the white surface geometry itself; the Notes fold is built into the white page surface itself. Original dark sphere detail vectors may resolve into the note strokes because they are existing material, not added layers.
