compileSdk 36 hard-codes a very new Android API level and will require consumers/CI to have that platform installed; this can reduce compatibility and break builds unexpectedly. Consider using a widely-available stable compileSdk (or making it configurable via a project property/ext), rather than hardcoding 36 here.
