/* ===========================================================================
  CSS Architecture
  - Tokens: :root custom properties
  - Base: html/body/typography/links
  - Layout: section spacing
  - Components: navbar, hero, cards, forms, timeline, program, sessions, submission/session details,
    special events, map, footer
  - Utilities: animations, accessibility, helpers
  Naming: BEM-ish for components; page-scoped rules are prefixed by page container where possible
  (e.g., .event .sessions-grid).
  Guidelines: co-locate responsive rules near their component; avoid duplicate selectors;
  prefer scoping over global collisions.
