+name: Fresh Install Tests
+
+# Periodically tests BlockNote with the latest versions of its dependencies
+# (within declared ranges), without a lockfile. This catches breakage when a
+# new release of a dep like @tiptap/* or prosemirror-* ships and conflicts
+# with BlockNote's declared ranges — the kind of failure a user would hit when
+# running `npm install @blocknote/react` in a fresh project.
+#
+# DevDependencies (vitest, vite, typescript, etc.) are still bounded by their
+# declared ranges in package.json; only prod/peer deps get freshly resolved.
