Workspace roots always sorted by name and only Maven/Gradle roots had a type icon. Project types are now detected from root build/SDK file names (no file contents or tools are read, up to four concurrent listings) through one registry (projectType.ts) that supplies names, icons, markers and refresh handling; roots show the type's icon, and Sort by Type groups roots by type with natural name order inside each type. Flutter and Vite logos come from Simple Icons (CC0, recorded in THIRD_PARTY_LICENSES.md).
