Ambient — component for backgrounds & gradients (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.

• Install: pnpm add @tsparticles/engine @tsparticles/slim @tsparticles/preset-<name>
• Registry: tsparticles · Framework: html · License: MIT
• Docs and preview: https://particles.js.org/demos/recipes/ambient
• Source: https://github.com/tsparticles/presets/blob/main/presets/ambient/src/options.ts
• Example: https://skills.varg.ai/previews/lib-tsparticles-ambient.mp4?v=20588 (Rendered by varg from the library’s own code (tsParticles · rendered by varg))
• Time: Drive from the frame. Runs on its own clock (requestAnimationFrame, timers, springs or CSS). Drive it from frame / fps before rendering, or the render drifts.
• Runs: local render, free
• Aspect: any

Use the tsParticles Ambient preset (https://particles.js.org/demos/recipes/ambient, MIT, options in github.com/tsparticles/presets/blob/main/presets/ambient/src/options.ts) as a calm full-frame background for an explainer, a quote or a lower-third heavy talking segment. Load @tsparticles/engine and @tsparticles/preset-ambient (or its CDN bundle tsparticles.preset.ambient.bundle.min.js), call loadAmbientPreset(tsParticles), then tsParticles.load({ id, options: { preset: "ambient", 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). Recolor the three particle groups and the background gradient to the brand, lower the particle count for a sparser field, and keep the speed low so it never competes with the text.
