View server responsible for rendering the widget tree to the terminal.

This gen_server manages the rendering lifecycle, including:

• Loading and applying CSS stylesheets
• Calculating layouts from widget trees
• Dirty checking to avoid unnecessary redraws
• Handling terminal resizes
• Managing the double-buffered rendering system

The view uses a dirty-checking optimization where it only re-renders when:

• The root widget tree has changed
• The terminal has been resized
• A forced redraw is requested

Rendering Pipeline

1. Widget tree → Layout calculation → CSS styling → Buffer rendering → Terminal output

Double Buffering

The underlying terminal backend maintains front and back buffers, only sending diff updates to the terminal for changed cells.
