# Waveshare ESP32-P4-WIFI6-Touch-LCD-4B — doorbell JPEG viewer (DRAFT)
# Square 720x720 IPS. Bring this up when the board arrives; the S3 yaml stays as-is.
#
# Touch cycles: stream A (default) -> stream B -> off -> stream A ...
#
# Notes:
# - ESPHome has a first-class 4C model (round 720x720), not 4B. Start with 4C;
#   if the panel looks wrong, switch to CUSTOM + Waveshare ST7703 init.
# - Wi-Fi is via onboard ESP32-C6 (esp32_hosted). Use fast_connect.
# - fast_jpeg still works as software decode initially; HW JPEG is a follow-up.
