Reviewer's GuideThis PR refines the dashboard artifact preview UX by tightening Markdown table header behavior, fullscreen table-of-contents sizing and keyboard interaction, and header alignment for the copy-path control, backed by new contract tests and Comet specs/archives.

**suggestion (testing):** Add assertions to ensure table body cells still wrap while headers do not
This test only verifies that headers use `white-space: nowrap` and that the container scrolls horizontally. It should also assert that body cells (e.g., `td`) are still allowed to wrap—for example, by checking that there is no `white-space: nowrap` rule targeting `td`, or that a wrapping-related rule for body cells is present if defined.

**suggestion (testing):** Extend Escape handling test to cover non-fullscreen behavior and listener cleanup contract
This test currently verifies that the Escape handler is added and removed, but not that it only applies in fullscreen. To better reflect the "closes only fullscreen preview" contract, consider asserting the `if (!isFullscreen) return undefined;` guard (or that the listener is only registered when `isFullscreen` is true). You can also strengthen the test by asserting the `useEffect` structure that handles listener cleanup, so the fullscreen-only behavior and cleanup are explicitly enforced.
Suggested implementation:
```typescript
it('uses the confirmed fullscreen directory dimensions and type scale', async () => {
const source = await readDashboardSource();
expect(source).toContain('w-[250px]');
expect(source).toContain('text-sm font-semibold uppercase');
expect(source).toContain("item.depth === 1 ? 'text-base font-medium'");
expect(source).toContain("item.depth === 2 ? 'pl-4 text-base'");
expect(source).toContain("item.depth === 3 ? 'pl-7 text-base'");
});
it('keeps only preview table headers readable and scrollable instead of wrapping', async () => {
const styles = await readDashboardStyles();
expect(styles).toContain('.md-github {');
expect(styles).toContain('overflow-x: auto;');
expect(styles).toContain('width: 100%;');
expect(styles).not.toContain('width: max-content;');
expect(styles).toContain('.md-github th {');
expect(styles).toContain('white-space: nowrap;');
});
it('closes only fullscreen preview with Escape', async () => {
const source = await readDashboardSource();
// Guard: Escape handling is a no-op when not fullscreen
expect(source).toContain('if (!isFullscreen) return undefined;');
// Handler: Escape key triggers close
expect(source).toContain("if (event.key === 'Escape') onClose();");
// Effect contract: listener is registered only in fullscreen and cleaned up on unmount
expect(source).toContain('useEffect(() => {');
expect(source).toContain('if (!isFullscreen) return undefined;');
expect(source).toContain("window.addEventListener('keydown', onKeyDown)");
expect(source).toContain("return () => window.removeEventListener('keydown', onKeyDown)");
});
```
If the actual implementation uses slightly different code (e.g. `return;` instead of `return undefined;`, or includes semicolons), adjust the `toContain` string literals to exactly match the source so the test remains stable while still asserting:
1. There is a guard that bypasses Escape handling when `isFullscreen` is false.
2. The `useEffect` encapsulates the `addEventListener` call.
3. The cleanup function removes the listener via `removeEventListener`.

**issue:** Several entries in the “Reason” column (A2–A8) appear misaligned with their corresponding acceptance criteria.
For A2–A8, the “Reason” text doesn’t align with the stated “Criterion” (e.g., A2’s criterion is about directory width and font sizes, but the reason mentions horizontal scrolling of table headers). Please adjust the “Reason” entries so each explicitly explains *why* that row’s criterion is required or valuable, and ensure the explanation matches the criterion content for every row.
