Not sure we can rely on storage because in a sandboxed iframe where most bot would be, touching sessionStorage would actually throw a security error. Might consider adding a try catch

export function enableBotDetection(): boolean {
  if (isBot()) {
    try {
      sessionStorage.setItem(TARGETING_DONE_KEY, "1");
    } catch {
      // storage unavailable (sandboxed iframe, cookies blocked), detection still stands
    }
    return true;
  }
  return false;
}
