   Reuses the exact design tokens and component conventions from
   index.html (color, type, spacing, radius, shadow, dark mode via
   [data-theme]) so this page reads as part of the same site, not
   a bolted-on module. New component classes are prefixed `atlas-`
   to avoid colliding with index.html's own class names.
