/* ==========================================================================
   The engine sites' calendar widget — shared by the booking widget
   (booking-widget.js, #booking-app) and the shifts widget (shifts-widget.js,
   #shifts-app). Both roots get the class .cal-widget; each widget keeps only
   its own rules inline. The accent is one variable, --cw-accent: booking keeps
   its cyan (--color-primary, undefined -> #06b6d4), the shifts page sets the
   site's colour. Loaded by booking.html / shifts.html, and by the widgets
   themselves on pages without those templates (the manage page).
