Word-Sweep Highlight — block for callouts & annotations (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.

A sentence whose word-by-word emphasis is driven by a single scalar — tween it to sync the highlight with a voiceover
