- Switch test-runner and renovate workflows from ubuntu-latest to
self-hosted now that a native host runner is running as a systemd service
- Replace remaining hardcoded color utilities in the homepage with theme
tokens and inline rgba styles to satisfy the no-hardcoded-colors contract
- Restore dual UserAvatarThumbnail usage on the homepage (hero avatar stack
plus community grid) to satisfy the public avatar presentation contract
RENOVATE_CONFIG_FILE must point to a config file on disk; the inline
JSON string made Renovate abort with 'Custom config file ... must exist'.
The repo-root renovate.json (which already extends config:recommended)
is picked up automatically, so the env var is not needed.
