Fireworks — component for particles & physics (html)

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.

Use the tsParticles Fireworks preset (https://particles.js.org/demos/recipes/fireworks, MIT, options in github.com/tsparticles/presets/blob/main/presets/fireworks/src/options.ts) as a full-frame night-sky background for New Year, launch or anniversary titles, or as an overlay on night footage with the background cleared. Load @tsparticles/engine and @tsparticles/preset-fireworks (or its CDN bundle tsparticles.preset.fireworks.bundle.min.js), call loadFireworksPreset(tsParticles), then tsParticles.load({ id, options: { preset: "fireworks", fullScreen: { enable: false } } }) into a full-frame div. tsParticles ticks on requestAnimationFrame and derives each step from the frame timestamp, so make it deterministic: seed Math.random before loading, swap requestAnimationFrame for a queue you flush once per video frame with the timestamp frame × 1000 / fps (keep fpsLimit at or above the video fps), and render frames in order from the moment it starts (it is a running simulation, so replay from that point after a backwards seek). The @tsparticles/fireworks bundle wraps the same effect behind a fireworks() call if that is simpler. Clear background.color to composite it over footage, lengthen emitters.rate.delay (0.3 s) for fewer, bigger moments, and set sounds: { enable: false } (the preset plays explosion sounds), since the audio belongs in the edit.
