# The compute core remains exposed through a plain C ABI, so one cdylib per
# platform covers every CPython version. Static chart export uses the focused
# `png` crate's fdeflate fast path; compression belongs beside rasterization so
# the hot path never round-trips a full framebuffer through Python.

# Whole-program optimization; `strip` keeps .dynsym, which ctypes binds
# against. `panic` must stay unwinding — lib.rs catches panics at the C ABI.
