/* ago.aeryx.ai, landing page only.
   Palette, type, scales and every shared component live in the aeryx brand:
   assets/vendor/{fonts,tokens,brand}.css, vendored from the aeryx-brand repo
   and guarded by cmd/sitegen/brand_test.go. Load order in site/index.html is
   fonts, tokens, brand, then this file.

   What is left here is what only ago has: the nav, the hero's accent line, the
   AST figure, and the footer. Nothing below may declare an --aeryx-* token. */
