How saranglab/qdte-project works

Sarang QDTE is a Rust terminal text editor. A user launches it with an optional file; the documented workflow is to choose or infer a keybinding profile, edit text interactively, and save or quit. The app coordinates editor state and file I/O; keymaps translate input into editor actions, while the renderer presents the buffer and status. README capabilities include search, Vim modes and commands, tutorials, configuration, and preservation of line endings and BOM. Some subsystem paths and links are documented rather than sampled; unsampled implementation details are not inferred.
