/*
 * Cosmo chat widget.
 *
 * Matches the site's existing language: square corners, hard offset shadows,
 * Space Grotesk with a mono label face, and the blue from apex-grid.css. The
 * tokens are redeclared locally so the widget renders correctly regardless of
 * stylesheet order, and every selector is scoped under .cosmo-root so nothing
 * here can reach the rest of the page.
 *
 * No blur, no gradient chrome, no emoji. Targets are >=44px, focus is always
 * visible, and each transition names its own properties so nothing animates by
 * accident.
