Pinned Mock, Changing States — effect skill for UI walkthroughs

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 how-to page 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 how-to page.

One product frame stays put while tabs or captions switch it through several feature states.

What it does

Built on Sticky Mock Swap by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

The mock holds center; a tab indicator slides between labels and the screen cross-fades to the matching state.

When: Walk through 3–5 features quickly without re-establishing the UI each time.

Watch out: Do not move the mock between states; stillness is what makes the changes readable.

Timing: Indicator slide 0.3 s, screen cross-fade 0.25 s, 2–3 s per state.

Also called: sticky mock, feature tabs, tabbed walkthrough
