## Why these overrides exist

This project requires all PRs targeting a release branch to skip
the standard labelling flow.

## Overrides

### Override 1 — Skip auto-labelling on release branches

For PRs whose base branch matches `v[0-9]-[0-9]-stable`, skip the
automatic label-assignment step. Apply labels manually for these PRs.
