Tea::CursedRenderer

Inherits Tea::Renderer < Reference < Object

Crystal idiom would use writer-style setters (logger=, color_profile=, width_method=), but this file keeps Go-parity method names. CursedRenderer is the main terminal renderer implementation It handles screen buffer management, cursor control, and terminal output
