/* ============================================================
   agenda — production stylesheet
   Direction: "Lily Pond" (soft Impressionist · frosted glass)
   A full-bleed Monet water-lily painting sits behind everything
   (.bg + .veil); content floats on frosted-glass cards. Dusty
   rose accent, sage + warm rose for states. Cormorant Garamond
   display + Mulish body.

   THEME LIVES IN :root — to switch directions, change these
   tokens + the .bg image; the rest is theme-independent.
