A vanilla JS dev tool that lets us preview multiple design options side-by-side on the same page.
- The user asks for multiple variants/options of a UI element (e.g. "give me 5 designs for X", "show a few options for Y", "create variants").
- The user is in a design exploration phase and wants to compare options live in the browser before picking a winner.
Do NOT use it for:
- A single design — just build the thing.
