# Signed-in app areas (dashboard, login, billing, shared bookmark links) are not
# for search: they render client-side for logged-in users. The block is repeated
# in every group because a crawler obeys only the most specific group naming it,
# and listed BEFORE "Allow: /" so first-match parsers agree with longest-match ones.

# AI *training* crawlers (GPTBot, ClaudeBot, anthropic-ai, CCBot, Meta-ExternalAgent,
# Amazonbot) are kept off the ~48K channel pages (/@…, /channel/…): each one runs a
# Cloudflare Function, and GPTBot alone made ~25K of them on 2026-10-14, pushing the
# free 100K/day limit over. AI *search/citation* crawlers (OAI-SearchBot, ChatGPT-User,
# Claude-SearchBot, Claude-User, Perplexity…) still read everything.
