/* Vault Strategies corporate site.
   Built on the same system as the Vault SE enrollment sites (Poppins, light pages, pill buttons,
   rounded cards, dark brand bands), with the corporate tenant palette: black bands and gold accents.
   Light tokens live on :root; .dark re-points the same tokens for black bands, so every component
   works on either without a second set of rules. Every text colour passes WCAG AA where it is used. */

/* One warm dark theme across the whole page, the way the SE sites' dark mode works: a single ground,
   surfaces a few shades lighter, ivory text rather than pure white. Small steps keep it continuous. */
