     * console.debug() and set Chromium DevTools to verbose log levels.
     * console.debug() shows as verbose in compute-go so you have to route those
     * to Log() if you want to see them:
     *
     *   // devvit-compute-go/internal/plugins/loggerplugin/logger.go
     *   case logger.Severity_VERBOSE:
     *     // there is no verbose.
