Vite compiles the mount path into the bundle, so it cannot be chosen at install
time from a single build - a page served under /shopdb would load and then
request its assets from /assets/, and render nothing.
build-site.sh now produces both:
frontend-dist base / - the app on its own IIS site
frontend-dist-subpath base /<alias> - an IIS Application under an existing
site, e.g. http://<server-fqdn>/shopdb/
SUBPATH_ALIAS (default 'shopdb') is fixed per bundle and written into the staged
build as .alias, so the three places that must agree - the IIS application alias,
MOUNT_PATH in .env, and this compiled base - cannot drift apart. The installer
checks that marker and refuses rather than serving a page that cannot load.
The subpath build runs FIRST and is held in a temp dir: the root build has to be
last so frontend/dist is left in the state a developer expects, and the copy into
$OUT has to happen after the staging step that does rm -rf "$OUT".
