# 4x WS2805 (5 channels each = 20 monochrome LEDs) on GPIO2.
# WS2805 is a 5-channel IC, but ESPHome addressable lights model max 4
# channels/pixel, so we drive the strip as plain RGB pixels and walk the raw
# channel bytes individually. 7 RGB pixels = 21 bytes, enough for the 20
# monochrome channels. Timing uses the WS2812 chipset preset (close to WS2805);
# switch to explicit bitN_high/low timings here if you see flicker.
