A comic sound effect going off in one corner: starburst, rays and halftone with the word on it, louder on every click, clear of your text.

Made as a Kadal Deck premium background, it fills whatever box you give it at its real size, in light and dark, and follows your brand colour (the --deck-accent CSS variable). Settings: words (the word for each step, split on "|": "beep | beep beep | kraka-boom!"), steps (loudness 0–1 before the first click, then one per click: "0.3 | 0.6 | 1"), focus (the corner it goes off in; keep the slide's words on the other side), ink (the burst, dots and rays), pop (the burst's core and the word's fill), pitch (distance between the halftone's dots, in stage pixels) and rays (speed rays fanning out of the burst).

What you get: a web component, one script with no framework, for a plain page, Webflow, WordPress or Framer, drawing behind your own content. A React component that also renders in Remotion. Stills at 2560 x 1440 in light and dark, and transparent ones to lay over a photo. A demo page to try the settings and print a PDF, and a README with a recipe for each.

In Kadal Deck, buying it unlocks SFX in every workspace you belong to (as background pro/sfx). Pro, Team and Lifetime plans include every premium background already.
