/* ─── CarSearch AI Partners — AI page (.pai-*) ───────────────────────────────
   Styles for public/js/partner-ai.js: the usage tab (range buttons, stat row,
   spend bars, dealership table, conversation drill-in) and the settings tab
   (dealership list, the per-dealership form, the apply-to picker). Tokens only,
   no literal colours, so every theme in app.css keeps working. Mobile target:
   390px wide with no page overflow and 16px inputs.                          */
