💠 Primordial Nucleosynthesis Abundance Curves (2D)

A 2D Canvas graph of Big Bang nucleosynthesis: watch hydrogen, helium-4, deuterium, and lithium-7 abundances trace out their classic curves as the early universe cools through the first minutes after the Big Bang. Adjust the baryon-to-photon ratio to see how it shifts the final primordial abundances, following the same semi-analytic BBN model (n/p freeze-out, deuterium bottleneck, Y_p ≈ 2(n/p)/(1+n/p)) used by cosmologists.
