  "caption": "Large specified seeds form contrast in smooth spherical matter at n\u22480.12 fm\u207b\u00b3, f_a=10\u00b9\u2076 GeV. A coherent seed normalized to the stated reference density instead remains tiny through 80 microseconds as the ordinary cloud expands. That linear response uses reciprocal zero-seed matter trajectories in a larger box with two grid/packet resolutions. The reference density is a design assumption. Matter removal is a separate intervention; its subsequent periodic contrast oscillates. These controls supply neither a stellar lifetime nor an astrophysical occurrence rate.",
