Pendulum Swing — primitive 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.

Content hangs from a fixed pivot and swings into rest with gravity-damped oscillation, like a hanging sign settling on its hook.
