- Add erikvl87/languagetool service on the internal network (port 8010, English only by default — change langsToLoad to add more) - 256 MB min / 512 MB max heap; healthcheck waits up to ~3 min for first startup while Java initialises - Server LANGUAGETOOL_URL hardwired to http://languagetool:8010/v2 — no character limits, no rate limits, fully private - Remove 40 000-char cap from lint route (not needed self-hosted) - Bump fetch timeout to 30 s for cold-start requests Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
