Editorial policy

Editorial principles

We distinguish official specifications, published sources, general training knowledge, and editorial experience. We state assumptions and uncertainty, and we do not mass-produce near-duplicate pages for search traffic.

Health and safety

This site does not diagnose or treat medical conditions. Stop running and seek qualified help for pain, dizziness, unusual breathlessness, or other concerning symptoms. Environmental awareness comes before music.
