 * site.css — Base styles for TLC Events client sites.

 * Layer architecture:
 *   1. Custom properties (design tokens — override per client)
 *   2. Reset / base
 *   3. Layout primitives (site-header, site-footer, site-main)
 *   4. Typography
 *   5. Components (event-card, category-tag, hero, etc.)
 *   6. Utility classes
 *
 * The calendar widget has its own scoped CSS loaded by calendar.js — these
 * styles only affect content outside the .tlc-cal container.
