+// class that handles low-level rendering operations, such as drawing pixels and shapes to the display.
+// This class is framework-agnostic and focuses solely on manipulating a 1-bit per pixel buffer.
+// Constructor Args:
+// uint8_t* buffer: Pointer to the bit buffer
+// int width: Display width in pixels
+// int height: Display height in pixels
