/*
 * Simple Booking Calendar – public styles
 *
 * Deliberately quiet: typography, text colour and sizing are inherited from the
 * theme. Everything visual is a custom property, so a theme (or the Custom CSS
 * field in the plugin settings) can restyle it, e.g.
 *
 *   .sbc-calendar { --sbc-booked-color: 180, 40, 40; }
 *
 * Colours are RGB triplets so opacity can be derived and the calendar works on
 * both light and dark backgrounds.
