64-day certificates are coming — and the dangerous change is the config edit you'd make in response

Let's Encrypt's default cert drops from 90 to 64 days on 10 Feb 2027. For a default Traefik/Coolify box, nothing breaks — the stock 30-day renewal window has margin to spare. The real trap is the 'helpful' edit of setting certificatesDuration to match, which shrinks your buffer from 34 days to 10.
