+-- backend writes to a device address, and that address is a board fact: the
+-- same binary on a second RISC-V machine writes to something that is not a
+-- UART and prints nothing. SBI's console is a call into firmware that already
+-- knows the machine, so one image runs under OpenSBI on QEMU's `virt` and on a
+-- real board without being rebuilt.
+--
+-- ⚠️ NO `deps`. The only mcpp dependency is the specification package, declared
+-- in this package's own manifest; nothing needs installing.

+-- (`-nostdlib`, `--subsystem,10`, `-e,efi_main`), which is not a workaround: a
+-- UEFI application IS PE/COFF with subsystem 10, entered through the Microsoft

+--
+-- An earlier analysis held that a new "PE freestanding" target would be needed
