Module mode 

Structs

ModeTransition

A one-shot transition request — emitted by the keymap, consumed by the editor loop.

Enums

CursorShape

The on-screen shape a cursor takes. A typed enum so the per-mode shape is a total, exhaustively-matched mapping (a new mode forces a new arm) rather than a renderer-local if mode == … ladder that can silently drift between backends.

Mode

Editor modes — vim-inspired with a small ceiling.
