SL-GlassesLed26x7: LED matrix pin mapping and replacement driver

SL-GlassesLed26x7 documents the connections of a 26×7 charlieplexed LED-glasses matrix and drives it with an ESP32 in place of the original controller. The repository records its pin layout and LED sections, with Arduino display examples and a bitmap generator.
