# Homelable served under a subpath (__BASE__) instead of the root of the origin.
#
# Generated at image build time by Dockerfile.frontend when VITE_BASE_PATH is set:
# __BASE__ is the prefix with its trailing slash, __BASE_NO_SLASH__ without it. A
# default build keeps docker/nginx.conf and this file is never read.
#
# The static build is copied to /usr/share/nginx/html__BASE__, so every block below
# uses plain `root` semantics — `alias` plus `try_files` mis-resolves $uri.
#
# Both reverse-proxy styles work against this config:
#   - prefix forwarded intact  (proxy_pass http://homelable;)  -> the __BASE__ blocks
#   - prefix stripped          (proxy_pass http://homelable/;) -> the trailing blocks
