A few minor items to address before merging:

1. Trailing ... on card style labels — 1/2 Card..., Blade Card..., Editorial Card... look like WIP artifacts. Other entries don't have them. Please clean up before merge.

2. [new] suffix on Use Rounded Corners label — "Use Rounded Corners [new]" is informal UI copy. Fine for now but should be tracked for removal once the feature is established.

3. Dependency on caas#444 — the PR description calls this out, but please confirm adobecom/caas#444 is merged before this goes to stage, otherwise the Button card style will appear in the configurator with no rendering backing.

4. secondaryCta URL redirect is untested — the cta2style === 'button' ? p.cta1url : p.cta2url logic in send-utils.js is the most non-obvious behavior in the diff and has no unit test. Worth adding a regression test for this case.

None of these are blockers for approval but items 1 and 3 should be resolved before the stage merge.

Good feature addition with solid test coverage for the new options. Left a comment with a few items to clean up before the stage merge — mainly the trailing '...' on card style labels and confirming caas#444 is landed. Nothing blocking approval. Approved.
