/* =========================================================================
   The built-in assistant — the launcher, the panel, and everything that
   renders inside it. Loaded by partials/head.liquid only when the server has
   an AI key (app.ai), so a workspace without the assistant ships none of it.

   Uses app.css's tokens throughout: same paper, same ink, rust only where
   something needs a person's attention (a proposal waiting, a credit warning).
