/* Lintel brand tokens and shared components for the apex site.
   Palette is a single indigo accent rendered at two tints: a deep shade for
   light mode (contrast on white) and a lighter, less saturated shade for dark
   mode (contrast on near-black). Both meet WCAG AA for text. Neutrals are a
   cool slate biased slightly toward the accent so greys read as intentional. */
