/**
 * Shared Calendar Styles
 * Base styles that can be extended by widget-specific CSS.
 *
 * Token-based (tokens.css via body[data-dir]) so the booking calendar matches
 * the rest of the design system — selection uses --accent (not a hardcoded
 * blue), surfaces/ink/lines follow the active direction (warm/crisp/minimal).
 * var() fallbacks mirror the "warm" direction so it still reads correctly
 * before the theme cascade resolves.
