Fireworks Background — component for particles & physics (react)

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/api/search?q=<what the person wants>" returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the use-case page.

Prompt that renders it frame-exact

Add the Fireworks Background from Animate UI (https://animate-ui.com/docs/backgrounds/fireworks, MIT + Commons Clause) behind a celebration moment: a launch, a milestone, a year-end card. Install with npx shadcn@latest add @animate-ui/backgrounds-fireworks and put <FireworksBackground className="absolute inset-0" /> under the text. The canvas advances one simulation step per requestAnimationFrame and uses Math.random, so it is not frame-exact: copy the component, swap Math.random for a seeded generator, and step the simulation exactly once per video frame (Remotion: in an effect keyed on useCurrentFrame(), replaying steps from 0 when seeking; HyperFrames: on hf-seek, simulate up to frame = time × fps). Tune population for density, color for brand colours, and the speed and size ranges.
