Detailed Description

Low-level LCD control API for Doly displays.

This header provides a minimal, low-level interface for initializing the LCD device(s), writing frame buffers, and controlling brightness.

Design notes:

Singleton-style control (namespace API; no instances)
Use init() before calling writeLcd(), setBrightness(), or buffer conversion helpers
Frame writes are performed per-side (LEFT/RIGHT)
