Pipeline

Pipeline Stage	Description	BrightScript / SceneGraph Notes
Text Node Initialization	Create `Label` or `TextField` nodes to hold ASCII characters	Use monospaced fonts for alignment (e.g., Courier)
Font Selection	Load a fixed-width font via `roFontRegistry` or `font` field in XML	Ensure font supports ASCII glyphs cleanly
Layout Grid	Arrange characters in a grid-like structure using `Group` or `LayoutGroup`	Manual positioning or use `RowList` for vertical stacks
Character Injection	Populate each node with ASCII strings or symbols	Use `text` field bindings or BrightScript logic
Refresh Trigger	Update nodes on input or timer events	Use `observeField` or `m.top.setField()` for updates
Rendering Pass	SceneGraph rasterizes text nodes in Z-order	ASCII art appears as layered text, not pixel graphics
Optimization	Minimize node count; reuse `Label` nodes for dynamic ASCII frames	Avoid deep nesting; cache static ASCII blocks
