 Already-ready mouse reports share a redraw: at most 64 reports are applied in their original order before painting, without dropping or summing away wheel steps. Readiness checks do not wait. The first non-mouse event is retained for the next iteration after rendering, so keys, paste, and resizes cannot reuse geometry from before their layout changes. The batch bound keeps continuous mouse input from starving drawing or background polling.

+Already-ready Insert typing and directly bound Normal/Visual document motions also share a redraw, with the same 64-key bound and non-waiting readiness checks. The editor classifies motion bindings, including remaps and comparison text panes, so the TUI does not hard-code navigation keys. Each key still passes through session dispatch separately, preserving counts, intermediate column clamping, Visual ranges, and history. Mode changes end a batch; pending key/operator/seek prefixes, focused lists/popups, non-motion bindings, release reports, and non-key events remain redraw boundaries. No repeat timer or acceleration is added.

 Ratatui's bounded layout cache is enabled: unchanged geometry and constraints reuse solved rectangles during scrolling; resizes and panel-layout changes use their own cache keys.

 The buffer viewport includes a fixed left gutter with right-aligned hybrid line numbers: the highlighted primary cursor line shows its one-based absolute number; every other line shows its distance from the primary. Secondary carets do not establish separate numbering origins. Width follows the total line count plus one separator cell, including an empty final row after a trailing newline; `git_gutter` bar/symbol modes add a blank cell and a marker cell between the number and separator. Number-color/none modes add no width. Horizontal scrolling affects only text; search/selection highlights and carets never paint over the gutter. Wrapped continuations and rows beyond the buffer have no number or marker. The gutter is hidden when it would leave no text column.
