# Policy: this is a public marketing/legal site with no confidential data.
# We allow search engines, AI answer engines, user-triggered AI agents, and
# model-training/grounding crawlers to access public pages, so AI assistants

# the matching public-site crawl permission, and /ai-notice.
# Do not publish confidential client data on this host.
# Review crawler tokens quarterly — they change often.
