# Allow AI ANSWER ENGINES that fetch on a user's explicit request (i.e. someone
# asked the assistant "what is 38-0?"). These surface us in AI answers during
# viral spikes and do NOT use the content for model training, so they are kept
# clear of the training-crawler blocks below. Reversible if posture changes.
