Bumped size limits:
|
Add an "Accept Bundlesize Increase" label-triggered workflow that automatically bumps failing size-limit entries in .size-limit.js with a min(10%, 1KB) margin. The workflow reuses build artifacts from the most recent CI run to avoid a full rebuild. Also improve the size-limit action failure message to list exceeded entries with details and instruct users about the label. Co-Authored-By: Claude <noreply@anthropic.com> Made-with: Cursor

Going to close this in favour of #19715 for the moment. We're not 100% happy with the CI-based approach because it needs to commit to the branch, making local development cumbersome. The skill seems like solid middle ground for now. We can revisit at any time. |

As a "manual but less manual than editing `.size-limit.js`" alternative to #19690, this PR adds a skill that takes care of bumping size limits. I also added a `test:size-limit` script for convenience since we didn't document elsewhere how to manually run the `size-limit` CLI.
