/* assets/site.css -- shared styles for the public content pages
   (daily-word, gallery, profiles, drawing permalinks).

   Design language is borrowed from the iOS app, not invented for the web:
   - "Cardstock" background: cool blue paper with subtle grain
     (PaperCoolBlue in AAABackgrounds/LCG.swift), dark purple in dark mode
     (PaperDarkPurple2). Grain here is an inline-SVG noise tile.
   - Content floats on a white "paper card" (PaperCard: 18pt continuous
     corners, hairline stroke, soft shadow).
   - Serif is the content voice (GalleryCellLayout): bold serif words
     overlaid on drawings with a doubled drop shadow, italic serif bylines.
   No gradient text, no gradient buttons. */
