# Starfield — block for particles & physics (hyperframes)

> **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.

Seek-safe night-sky overlay: sparse or dense stars in three size tiers that twinkle and drift in two parallax layers, radial-masked to keep the frame center clear
