/* ---------------------------------------------------------------
   Aman Trivedi — personal site
   A notebook, not a brand page. Two type families, one accent,
   margin notes for meta. Nothing else is trying to get your attention.

   Changes from the first version: --ink-faint darkened/lightened so
   small meta text passes WCAG AA (it was ~3:1); layout helpers for the
   generated pages (tables, related links, focus list, preview banner).
