CellRenderer

Comptime cell renderer. You supply hooks for cursor shape, hyperlink hits, and selection highlights. 
const vte = @import("otter_vte");

const Hooks = vte.CellRendererHooks(MyCell, MyState);

var renderer = vte.CellRenderer(MyCell, Hooks).init(&state);
try renderer.drawGrid(&cmds, visible_rows, visible_cols);
textRunBatchingSafe reports whether adjacent cells can merge into one text draw call (same style, no wide-char boundary).

​
Renderer facade

vte.Renderer wraps command list allocation, damage rects, and quad_renderer playback for simpler embedders.

​
Integration with otter-term

otter-term maps Ghostty screen cells into MyCell, wires PTY resize, forwards pointer selection. New terminal drawing belongs in hooks here, not copy-pasted in the app.
