void	draw (DrawContext context) override
fl::string	fxName () const override
void	setAmbientBrightnessDecay (float decay)
	Per-frame brightness decay for ambient particles.
void	setAmbientPalette (const CRGBPalette16 &palette)
	Set palette for ambient particles.
void	setAmbientTrailIntensity (u8 intensity)
	Ambient trail intensity: 0 = no trail, 255 = long persistent trail.
void	setDebrisBrightnessDecay (float decay)
	Per-frame brightness decay for debris particles. Default 0.90.
void	setDebrisVelocityDecay (float decay)
	Per-frame velocity decay for debris particles. Default 0.95.
void	setDrag (float drag)
	Set per-frame drag for ambient particles (0.0 = instant stop, 1.0 = no drag).
void	setMeteorGradient (CRGB headColor, CRGB midColor, CRGB tailColor)
	Set the meteor color gradient: head → mid → tail.
void	setMeteorTrailIntensity (u8 intensity)
	Meteor trail intensity: controls how long meteor/debris trails linger.
void	setMinVelocity (float minVel)
	Minimum velocity before a particle dies.
void	setNoisePalette (const CRGBPalette16 &palette)
	Set palette for Perlin noise background.
void	setSpeed (float speed)
	Set velocity multiplier. Default 1.0.
void	setTimeMultiplier (float mult)
	Set time multiplier for noise evolution (1.0 = normal, >1 = warp).
void	spawnAmbient (float intensity=0.5f)
	Spawn an ambient particle at a random position.
void	spawnMeteor (float intensity=1.0f)
	Spawn a BEAT meteor at position 0, traveling toward end of strip.
