/* ==========================================================================
   ERAM SURVEYS — main.css
   Design System (tokens), reset, base layout, header, footer, section content
   and the motion-layer hooks.

   CSS naming convention (project-wide, BEM-like):
     .block            component root            e.g. .site-header, .nav
     .block__element   part of a block           e.g. .nav__link, .card__title
     .block--modifier  variant of a block/elem   e.g. .btn--primary, .is-open (state)
   State classes use the `.is-*` / `.has-*` prefix (e.g. .is-open, .is-active).
   Layout helpers are prefixed `.u-` (utilities) or `.l-` where needed.
   Design tokens live in :root below and MUST be reused across the stylesheet.
