### Task Summary
`HuggingFaceImageUploadComponent`'s **template** is at ~39%
(`hugging-face-image-upload.component.html`, 11 uncovered lines of 51) while
its class file is already at **100%** — the handlers are unit-tested, but the
preview panel never renders, so its bindings stay uncovered. Bring the template
to full coverage. Vitest/jsdom; see `frontend/TESTING.md`.
### Behavior to add
Extend `hugging-face-image-upload.component.spec.ts` so the preview branch
renders, then run the coverage report and cover the remaining red lines. The
gap is the selected-image panel: the `<img [src]="previewSrc">`, the
`hf-image-meta` block with `{{ displayFileName || "Selected image" }}`, and the
`(click)="clearImage(fileInput)"` button.
Approach:
- Put the component in the "image selected" state (set `previewSrc` /
`displayFileName` through the same path the component uses) and
`fixture.detectChanges()` so the preview panel renders.
- Assert the `img`'s bound `src` and the displayed name, plus the fallback
text when `displayFileName` is empty ("Selected image").
- Click the clear button via `fixture.debugElement.query(By.css("..."))` +
`.triggerEventHandler("click", ...)` and assert `clearImage` reset the preview
state (the panel disappears after a further `detectChanges()`).
Assert on rendered attributes/text — not on layout or geometry (zeros under
jsdom).
