/**
 * Chatbot widget — floating button + panel, site-wide.
 * Uses the theme's existing design tokens (assets/css/becker-main.css).
 *
 * Elements toggled via the native `hidden` attribute (panel, body,
 * input-row) also set an explicit `display: flex` for when they're
 * shown — author CSS always wins over the browser's built-in
 * `[hidden] { display: none }` rule, so without the `[hidden]`
 * overrides below those elements would stay visible even while hidden.
