Constant CONTENT_CREATION_PER_MINUTE 

pub const CONTENT_CREATION_PER_MINUTE: u64 = 80;

GitHub’s published ceiling on content-generating requests, per minute.

Pinned in tests/fixtures/rate-limits.json and gated against it, because it is GitHub’s number rather than this source’s: MIN_MUTATION_INTERVAL_MS is derived from it, so a pacing value checked only against itself cannot go stale here.
