+# Design Studio 0.1.1 — Linux preview lookup
+
+Composed and gallery previews previously inferred a component's filename from
+its public name (Input -> Input.wrn). Some shipped components use lowercase
+filenames (input.wrn), so the lookup happened to work on Windows and failed on
+Linux with ENOENT. Previews now use uiComponentPath from the shipped UI registry,
+which resolves declared names to their exact source files, including ComboBox.
+
+A subprocess regression test enforces exact filesystem casing even on Windows
+and renders the composed preview and all seven gallery pages (104 components).
+All 42 Studio tests and the workspace TypeScript check pass. Existing component
+APIs, design schemas, browser drafts and generation contracts are unchanged.
+
+Private package publication and the standalone component site's dependency pin
+are updated as part of this fix. The VM must install the updated lockfile,
+rebuild and restart before the live preview error can disappear.
