DynamicCommandList extends the render command model for terminal cells: backgrounds, glyph runs, powerline segments, underline styles. 
const vte = @import("otter_vte");

var cmds = vte.DynamicCommandList.init(allocator);
defer cmds.deinit();

// Record cell draws for the visible grid
// Attach TextSystem + ShapeScratch for RTL/CJK through otter-render
cmds.text_system = &text_system;
cmds.text_scratch = &scratch;
Reset or reuse the list each frame like DefaultCommandList. Terminal views often damage row bands instead of the full grid.

​
Text shaping

When text_system and text_scratch are set, text commands use HarfBuzz shaping and font fallbacks from otter-render. Plain ASCII can omit them for the FreeType fast path.

​
Playback

Rasterize with otter-render quad_renderer, passing terminal damage rects for row-level culling.
