nginx.container.conf

# One site: the static build of site/, served at the apex.
# The host nginx forwards the Host header; anything that is not an old host
# below (the apex, the health check's 127.0.0.1) gets the site.

# Until 2026-09-27 the docs lived on docs.reactmarkdownkit.com, each demo on
# its own subdomain, and www served a copy of the old home page. Each old
# host moves permanently to the apex, in one hop, so search engines carry
# each page's ranking over. A demo host had one page, `/`; it goes to the
# demo's path with its query (`?embed=1`, `?view=`), and the browser keeps
# the hash that carries a shared document. Keep these redirects for good.

# The two ownership files stay reachable on every old host without a

# Webmaster Tools, which both need it verified to process the site move.
