esphome-guition-jc3636k718c-va

Reference for building/editing ESPHome configs on the Guition JC3636K718C round knob display (ESP32-S3, 1.8" 360x360 ST77916, CST816 touch, rotary knob, PCM5100A DAC, PDM mic, WS2812 LED ring). Use whenever working on this board (or the base/core.yaml in this repo): correct pinout, ESPHome component choices, and the hard-won gotchas (knob isn't quadrature, GPIO0 ring strapping, 16 MB partitions need USB flash, LVGL performance limits, lambda/string pitfalls, battery is heuristic).
