/* Earnest — earnest.grcsac.com
   A two-colour identity: plum and ivory trade places between modes.
   Night (default) = plum ground, ivory accent. Day = ivory ground, plum accent.
   Body text is tuned a notch off the accent in each mode so the accent still
   reads as an accent rather than merging with the text.
   Serif voice, self-contained (system fonts only — no external requests). */
