 * AI Assistant: its button and its window (WBAMS add-on mtd_ai_assistant).
 *
 * Colours come from the site's theme: Draisap's and Draynur's --dr-* tokens, Serepok's --mtd-* ones, the CMS's
 * --primary. Dark mode follows the theme (body.dark-mode on Serepok, html[data-theme="dark"] on Draisap and Draynur).
 * The window is one surface: hairlines, a segmented control, pictures and buttons inside it, never a box in a box.
 * On a phone it is a full-screen sheet. Everything is scoped under .mtdai-* so a theme's own rules stay out.
