   Aptos everywhere (headings + UI chrome) - it's a Microsoft system font, not
   web-hosted, so it only renders for visitors who have it installed (Windows
   11 24H2 / Office 365); everyone else gets Manrope, a similar humanist sans,
   as a same-spirit fallback. IBM Plex Mono still carries ticker/numeric values.
   Built on a small Tailwind-style token scale (spacing / type / radius / shadow).
