/* =====================================================================
   Lutastic+ — landing page

   Built on the shared design tokens (palette, type, spacing, motion).
   Page-level theme tokens (`--page-*`) bridge the design system to this
   page and swap on `[data-theme-mode]`. Light is the default — no
   attribute required; dark is opt-in via the theme toggle.

   The `.site-lutastic` body class plays the role of the page shell
   (flex column, shared horizontal padding, decorative glow). nav, hero
   and footer are direct flex children rendered through base.html.
