# Stage 1: Builder
# We use a lightweight Wolfi image to gather the files. 
# In a real build process, this might involve 'npm run build', but for static files, 
# we just copy them. Using a stage here allows for future extensibility.

# Stage 2: Final
# Use the official Wolfi base image and install Caddy manually
# since the pre-built Caddy image requires authentication or is restricted.
