/**
 * TMS Calendar Widget Styles
 *
 * Mobile-first: design for ~360px screens, then enhance for desktop.
 *
 * Visual language:
 *   green    = available, bookable
 *   red      = fully booked, not bookable
 *   amber    = collection unavailable (for collection bookings only)
 *   grey     = closed (weekend, bank holiday, past date)
 *   selected = blue border + light blue fill
 *
 * The widget renders into a <div id="tms-calendar-widget"></div> that the
 * booking form provides.
