In @.github/workflows/ci.yml:
- Line 85: Update the changed-path filter that assigns the gateway flag to
include packages/web/ alongside the existing gateway-related paths, ensuring
web-only changes set gateway=true and trigger the gateway-service delivery gate.
In `@scripts/nginx-web-delivery-acceptance.mjs`:
- Line 130: Update the asset selection in the acceptance test to choose a
non-source-map JavaScript file meeting the 1024-byte gzip_min_length threshold,
or validate that the selected asset satisfies this size before gzip assertions
run; preserve the existing failure behavior when no suitable asset exists.
- Line 347: Update the WebSocket client creation in the acceptance test to pass
the public Nginx URL through the supported origin option, ensuring the handshake
includes an Origin header for same-origin validation. Keep the existing ws
connection target and surrounding test flow unchanged.

- Around line 137-140: Update the asset selector near hashedCssFile so it only
accepts CSS files matching Vite’s hashed asset filename contract before checking
size; alternatively, derive the expected CSS filename from the generated
manifest if available. Preserve the existing exclusion of source maps and
minimum-size requirement, and ensure the immutable-cache assertion cannot pass
with an unhashed file such as app.css.
