Is the coin truly 50/50?

Yes — the flip uses crypto.getRandomValues(), which is uniformly distributed. Over many flips you should converge to 50% heads and 50% tails.

Why does my count look uneven?

Small samples can drift 40/60 easily — that's normal variance. The expected deviation shrinks as √N. At 1,000 flips, ±3% is typical.
