/*
 * Styling for the chirp widget (see chirp.html/.js). Lives beside its
 * template/behavior siblings, discovered and linked the same way -- see
 * ../canary/WIDGETS.md. Relies on the color tokens framework.css defines
 * on :root (--bg, --bg-elevated, --text, --text-dim, --border, --accent);
 * those cascade globally once defined, regardless of which stylesheet
 * file references them, so this file doesn't need to redefine or import
 * them -- same reasoning as slideshow.css/downloads.css.
