/* Embeddable widget (/embed/widget). Self-contained: this file and widget.js

 * Hand-written, not Tailwind: app.css is ~250 KB and built for /site/.

 * Fills its iframe edge to edge (the host page draws the border). Opened as a
 * page of its own (html.wv-standalone) it sits as a card in the middle.
 * Themes: <html data-theme="light|dark|auto">; auto follows the visitor. */
