description: Stacked-PR workflow — split work into a chain of dependent PRs (each layer <200 lines, 1 concern, --base on the layer below). Uses gh stack where enabled, else the manual gh pr create --base fallback. Triggers — "split into stacked PRs", "stack these changes", "make a PR chain", "rebase the stack".
