The burst test: click anywhere. A krackle detonation should bloom outward from the click point — inner masses first, outer bands ~55 and ~110ms behind, everything decelerating as it drifts — with 2–4 clean white rays radiating through it and a clear halo at the center. Masses should be thick near the source and dissolve into scattered dots at the rim. Then it fades: full ink for about the first 60% of its life, then gone.
What should NOT happen: no krackle while moving the mouse. No krackle while scroll-dragging on a phone — only a completed tap bursts. No burst from keyboard-activating these buttons. And a few seconds after the last burst fades, the loop should be fully asleep.
Also verify: theme flip regenerates rimmed sprites (click in dark mode — black masses with paper rims), rapid clicking recycles the pool gracefully rather than growing it, and the power button's destroy() leaves no canvas and no listeners.
Lorem kirbium: the bombastic machinery of the cosmos grinds on, indifferent to deadline or drama, each panel a detonation frozen mid-blast. Galactus hungers; the Watcher watches; the ink pools in impossible black masses around every energy discharge — but never on the energy itself. The white is the power. The black is everything the power pushed aside.
More filler to force scrolling on phones. The Source Wall looms. The Mother Box pings. Somewhere in the Negative Zone, Annihilus taps his cosmic control rod against the void and watches the detonation carve its white rays through the dark, band by band, until the last dot dissolves.
