   Rensora Design System — typography tokens
   Source: "Rensora Design System final" (project/tokens.css).

   Custom properties only — no @font-face and no element rules, so this file
   never changes the typeface a page renders in. The site sets its own faces
   in each page's <style> block.

   Aptos is not bundled: its Microsoft licence covers desktop and Office use,
   not self-hosting on a public web server. The stacks below fall through to
   Inter / system fonts wherever Aptos is not installed.
