Planck's precise measurement of CMB temperature anisotropies matches the six-parameter ΛCDM model, fixing the universe's age, geometry, and composition (~5% ordinary matter, ~27% dark matter, ~68% dark energy).
CMB acoustic peaks require cold dark matter.
The CMB peaks are very hard for MOND without adding dark matter.
ΛCDM fits the CMB with a cosmological constant.
