# The runtime executes each user function inside a locked-down Deno isolate
# (BRIVEN_RUNTIME_EXECUTOR=deno — the multi-tenant security boundary). The base
# image is Bun, so the `deno` binary is copied in from Deno's official image.
# Without it the executor fails with: Executable not found in $PATH: "deno".

# Create the bundle dir and chown it BEFORE switching to the non-root user.
# compose mounts the `runtime_bundles` named volume at /var/lib/briven/bundles;
# a fresh named volume inherits the ownership of this image directory on first
# creation, so it must already be app:app or the non-root process gets EACCES
# when it mkdir's the per-project bundle subfolder (bundle_fetch_failed).
