Scribble Transition — 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.

Overlay transition: scribble bands accumulate to cover the frame with a solid backstop, the host cuts beneath, and the scribble clears
