 # Restore Mobile Terminal Scrolling — Tasks
 
 - [x] Add a mobile-specific terminal scrollback limit while preserving zero scrollback on desktop.
+- [x] Reinitialize the terminal when the responsive mobile classification changes so its scrollback and touch handler match the active viewport.
 - [x] Add focused tests for the responsive scrollback configuration.
 - [x] Run the full frontend test suite (89 tests passed after repairing the `ProjectsPage` test setup).
 - [x] Run frontend typecheck, lint, focused tests, and production build.
