Initial commit — Amirine Cosplay Lights

Arduino Uno + WS2812B LED strip controller with a text-based lightshow
system. Shows are defined as .txt files (hex color + fade duration per step),
converted to PROGMEM headers by convert_all.py, and navigated at runtime
via a debounced button (tap/double-tap/hold). BSD 2-Clause license.
