Self-hosted collaborative editing for DOCX, XLSX, PPTX, and ODT files.
Integrates with Nextcloud and FileBrowser Quantum.
Port: 8082 (internal 80)

## JWT Secret
Stored in \`.env\` (chmod 600). If you rotate it:
1. Update \`JWT_SECRET\` in \`.env\`
2. Re-run the installer to re-wire all integrations:  \`sudo bash services/onlyoffice.sh\`

## Verify integrations
\`\`\`bash
# Nextcloud
docker exec --user www-data nextcloud php occ config:app:get onlyoffice DocumentServerUrl
docker exec --user www-data nextcloud php occ config:app:get onlyoffice jwt_secret

# FileBrowser Quantum
