# ---------------------------------------------------------------------------
# Nginx static sitemap file serving
# ---------------------------------------------------------------------------
# Compatible with the production skinbase.org vhost, which has NO named
# location @php. Laravel is already wired as:
#
#   location / {
#       try_files $uri $uri/ /index.php?$query_string;
#   }
#   location = /index.php {
#       fastcgi_pass unix:/run/php/php8.4-fpm-skinbase.sock;
#       ...
#   }
#
# Do not add `try_files ... @php` — that named location does not exist on
# server3 and nginx -t / runtime would fail (or 500) when the static file
# is missing.
#
# GenerateSitemapsCommand writes:
#   public/sitemaps/index.xml     <- canonical generated root index
#   public/sitemaps/sitemap.xml   <- legacy filename (best-effort)
#   public/sitemap.xml            <- legacy $uri (often unwritable on prod)
#   public/sitemaps/{name}.xml    <- child / shard documents
#
# Place these location blocks BEFORE `location /` is not required if they are
# more specific (`=` and regex), but they must remain inside the 443 server.

    # sitemaps/sitemap.xml, then Laravel front controller (not @php).
