# Build the Admin2 SPA directly into the plugin's app/ directory.
#
# The SvelteKit build emits a token placeholder as its base path; the PHP
# plugin substitutes the token for the configured route at serve time, so
# the build is route-agnostic and does not need rebuilding when the route
# changes.
#
# Usage:
#   ./bin/build.sh                          # Build from default location
#   ./bin/build.sh /path/to/grav-admin-next # Build from custom location
