/* Calendar & Booking Tile Styles
   File: /www/css/style.css
   Purpose: Styles for multi-column calendar layout, per-staff columns,
   booking tiles, responsive behavior, and modal form spacing.

   Customize colors and layout below by editing the CSS variables
   inside .calendar-container. Selectors are scoped to avoid affecting
   unrelated site styles.
