   PersivX Docs — design tokens.

   The brand is two colors, sampled from the wordmark: navy #242E3D ("PERSIV")
   and sage #ACC3A6 (the "X"). Sage at its brand value is only 1.9:1 on white,
   so light mode uses a deepened sage (#4C7547, 5.3:1) as the accent and saves
   the literal brand color for dark mode, where it lands at 9.6:1 on #171614.
   Navy carries headings and body ink in light mode.
