Why: This loader starts without the normal C startup code. That means no one copies .data or clears .bss before the loader runs. If a future change adds global writable data, it could act wrong on the Playdate. This makes the linker stop the build if that unsafe state is added before real startup support exists.

Summary
Why
This loader starts without the normal C startup code. That means no one copies .data or clears .bss before it runs. If a future change adds global writable data, it could act wrong on the Playdate. This makes the build stop until startup support exists.
