//! `-Wl,-export_dynamic` keeps the test binary's symbols in its dynamic
//! symbol table — originally so the M12 P0 decode bridge could resolve
//! the oakcodec C ABI with `dlsym(RTLD_DEFAULT)` (the decode bridge is a
//! direct Rust call now). It is spelled the macOS way and is therefore
//! emitted on macOS only: on ELF platforms lld parses `-export_dynamic`
//! as `-e xport_dynamic` and links a binary with NO entry point, which
//! then dies with SIGSEGV inside ld.so at startup (Rust >= 1.90 links
//! x86_64-unknown-linux-gnu with rust-lld by default). The macOS
//! framework flags below are the load-bearing part: the bundled
//! OpenColorIO's system monitor references IOKit / ColorSync /
//! CoreGraphics display APIs.
