Rounds out the sampler with the remaining effects:
- bloom — a filled diamond grows from the centre to full, then collapses.
- breathe — a dithered shimmer that swells and fades (density ramp via a
fixed per-pixel threshold, since the matrix can't truly fade).
- checker — a checkerboard that inverts on each beat.
Full cycle is now rain -> knight-rider -> comet -> ripple -> bloom ->
breathe -> sparkle -> checker -> wipe. Compiled + flashed E2E (2057 bytes).
