Default site (no folder for this host)

This is html/_default/ — the fallback served for any host that doesn't have its own folder. To add a domain, create a folder named after the host and drop files in:

html/
  _default/        ← you are here (fallback)
    index.html
    404.html
  example.com/     → served for example.com
    index.html
    about/index.html
  127.0.0.1/       → served for 127.0.0.1:5555 (local dev)
    index.html

The host's port is ignored, so 127.0.0.1:5555 maps to the 127.0.0.1/ folder. www. hosts 301 to the apex.
