 * Brand: blue #2049d1 (hover #1135af), navy #053350, deep navy #032336, light blue #e8f1f6, Montserrat + Open Sans.
 * public/assets/booking/widget.css (the inline widget on the website) is GENERATED from this file: after a change here
 * run "php tools/build-widget-css.php" (it scopes every rule under .dlb-widget; the tests fail when it is stale).
