/* Koot AI (External) — BYOK cloud AI icon-button + modal.
   Additive only: new classes, does not override anything in style.css.
   The trigger button itself (#koot-ai-ext-btn) reuses the existing .btn-icon
   style so it matches the search/add-contact icons; this just adds a small
   dot to show when a provider is connected. */
