+- **fix(ci):** the blocking "Impacted unit tests (TIA)" step false-redded any PR whose impact graph reached a dashboard component — it ran every selected test under `--import tsx/esm`, but `tests/unit/dashboard/**` requires the `--import tsx` CJS transform (ESM-only deep imports like `@lobehub/icons/es/*`), exactly as the canonical `test:unit:ci:shard` already does per segment. The impacted selection is now split by segment with matching loaders (closes #6787).
