/* greetings — Croft design palette (Phase 2), aligned with crofting_site: an
   earthy, tectonic system. Serif display (Lora, Georgia fallback), sans body
   (Inter, system fallback); ruddy is the primary action, moss the link/active,
   granite the subtle text, on an oatmeal canvas. Light/dark via the pre-paint
   [data-theme] attribute. Kept lean; richer card theming arrives with the cards.
   (Self-hosting the Lora/Inter woff2 files is a later polish; the fallbacks keep
   the structure croft-consistent meanwhile.) */
