/* ==================================================================
   AI Setup — Local (browser) models card
   ==================================================================
   Injected into the AI Setup modal (`.modal-overlay > .modal` with an
   "AI Setup" header). Adds a "Local (browser)" card with the 3 in-browser
   providers (wllama / WebLLM / Transformers.js), download + install with
   progress, an installed-models list, and a "Use this model" activation.

   Uses only root design tokens from assets/css/base.css. No shared
   component classes are redefined.
