A cursed vellum on a timber desk. Draw freely. Two fingers, a long press, or Shift uses pale chalk that muddies gall ink into a scar, never a hole. Drag the roll at the right edge or pull the top curl slowly to close this page; a new blank sheet unfurls. There is no undo. A screenshot is the only save. Keyboard: arrows or WASD move the quill, Space or Enter draws, Shift holds the chalk end.
