• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Check that this is a concrete bug. For Q&A open a GitHub Discussion or join our Discord Chat Server.
• The provided reproduction is a minimal reproducible example of the bug.

The report points to docs/.vitepress/config.ts and the docs:dev script. Start by reproducing the restart loop after changing config.ts, then trace the dev-server behavior around that configuration. Done means a config change reloads the docs without repeatedly restarting the server.
