Rapid halo growth in SEEDZ simulations enables heavy black hole seed formation via supermassive stars at a comoving number density of 0.1 cMpc^{-3} by z=10, with most seeds in near-solar metallicity gas.
High-resolution simulations produce compact galaxies where gas inflows and dynamical processes accumulate enough mass in 10 Myr to form ~10^6 solar mass central black holes under 10% feedback efficiency.
