reproduce:
bun install --frozen-lockfile
bun run dev
and open "http://localhost:5173/binary" in your browser. PNG image should be displayed (1px x 1px, only one red dot).
bun run build
and open dist/binary.png in your image viewer. It expected to be only one red dot, but it's broken in binary level.
