  "caption": "Actual 15-solar-mass MESA tracks at Z=0.02. The star adjusts its temperature after an imposed resonance shift, but substantial central carbon/oxygen differences remain. The photon scenario combines +200 ppm alpha, its +0.798 keV Hoyle response, and the fixed-input capture calculation with a 50% ground-state fraction. Ordinary EOS, opacities and weak rates remain in use. Central fractions are not ejected yields; mesh/time refinement and ordinary wind/mixing alternatives are in the report.",
