Rule: documentation PRs are reviewed by a human, never the bot

Scope: documentation-only PRs (the documentation-ticket workflow) — changes confined to the README, docs/, any .md file, or plain text/typo fixes, with no source-code changes.

Prose is judged by people, not by a code reviewer. Therefore, for a docs PR:

• You MUST leave the review to a human.
• You MUST NOT request the Copilot reviewer (scripts/request_copilot_review.py) on a documentation PR.
• You MUST NOT merge until a human has approved it.

If you are unsure whether a ticket is documentation or code, it is not a docs ticket — treat it as code and follow tests-first and merge-on-clean-review instead.
