Limits

4th & Heart publishes no rate limits that could be read; the profile records that absence rather than inventing a ceiling.
A rate limit is documented in prose but never quantified, and no rate-limit headers were returned on observed 200 responses. limit_count is 0 because no numeric limit is published anywhere — an honest zero, not an unchecked field. The 429-and-back-off contract below is real and is what an agent actually gets.
