/* BYOME site — Paper (light) and Night Lamp (dark), matching the app's two themes.

   Each palette is defined exactly once below; the theme switch only remaps which
   palette the live tokens point at.

   Deliberately var() indirection rather than light-dark(). light-dark() works when
   written straight into a property, but wrapping it in a custom property did not
   resolve reliably here — tokens defined that way failed to flip when the toggle
   changed color-scheme at runtime. Remapping custom properties invalidates
   correctly and keeps one definition per palette. */
