/* Covenant (working name) — design system.
   The feel: a beautifully printed wedding invitation. Warm ivory paper, deep
   brown-black ink, candlelight gold, a quiet sage. Fraunces for display,
   Newsreader for reading. Hairline rules, small-caps labels, portrait mats.
   Nothing neon, nothing glossy, no purple, no pink gradients. */
