Overview

Abstract renderer interface for terminal output.

Separates rendering logic from I/O operations, enabling different renderer implementations (terminal, in-memory, etc.).

This interface defines all methods that Buffer requires for rendering cells to the screen, including cursor control, colors, and attributes.

Note: Methods with _seq suffix write escape sequences immediately. This distinguishes them from buffer state management methods.
