# Duotone Beat — primitive for beat sync (remotion)

> **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.

A two-ink halftone portrait swaps its ink pair on every beat, with a punch-in on the downbeat and a bar indicator.
