The toolbar download button now uses the already-fetched download URL
from useQuery (zero extra requests), while tree node downloads keep
using useMutation with React Query-managed isPending state instead of
a hand-rolled useState wrapper.
Implement ReadOnlyFilePreview to render sandbox files by type
(code, markdown, image, video, SQLite, unsupported) using existing
skill viewer components with readOnly support. Add
useSandboxFileDownloadUrl and useFetchTextContent hooks for data
fetching, and generalize useFileTypeInfo to accept any file-like
object.
Extract shared empty state card into ArtifactsEmpty component to
deduplicate the no-files and no-selection empty states. Align the
split-panel right-side empty state with the variables tab pattern.
Remove FC type annotations in favor of inline parameter types.
Mark the empty state SearchLinesSparkle icon as aria-hidden for screen
readers. Replace array-index keys with cumulative path keys (O(n) vs
O(n²)) to satisfy react/no-array-index-key and improve key stability.
Replace the minimal centered text card in artifacts tab empty state with
a full-height card layout matching the variables tab, including icon
container (SearchLinesSparkle), title, description, and learn more link.
- add SplitPanel to share left/right shell and narrow menu handling
- reuse InspectHeaderProps for tab header + actions across tabs
- refactor variables/artifacts tabs to plug into shared split layout
- align right-side header/close behavior and consolidate empty/loading flows
Consolidate duplicated TabHeader + close button layout (8 occurrences) into a single
InspectLayout wrapper. Replace boolean props with children slots for better composition.

Refactor the variable inspect panel into a tabbed layout with Variables
and Artifacts tabs. Extract variable logic into VariablesTab, add new
ArtifactsTab with sandbox file tree selection and preview pane, and
improve accessibility across tree nodes and interactive elements.
