# MUST run from internal/http/spa/ so the relative LocalBasePath
# ("../../../frontend/dist/") resolves to the actual frontend/dist/ directory.
# Without this, the Go binary serves stale packr-embedded frontend files.
#
# Usage:
#   ./start-spire.sh 3010        # Start production (foreground)
#   ./start-spire.sh 3010 -d     # Start production (daemon)
#   ./start-spire.sh 8081 -d     # Start dev (daemon)
