common/status_led_atom.yaml puts common/status_led.yaml on the ATOM Lite's
own RGB LED (G27, 64 RMT symbols to leave room for IR/RF). echo-1 uses its
existing LED light.
The i2s_audio media_player platform was removed; rebuild the audio
pipeline like mcu-echo.yaml with an i2s_audio speaker feeding a
mixer, so media playback, TTS announcements, and rtttl beeps all
share the one physical DAC output without conflicting. Also uses
format: NONE instead of the deprecated codec_support_enabled.

Bulk cleanup: remove trailing whitespace and ensure files end with a
newline. Structural issues (indentation, bracket spacing) left for
per-file fixes.
