   One set of rules for every page. Loaded after style.css,

   or a color, take it from the list below. Don't invent new
   ones.

   TYPE: five sizes, three fonts
     display   the one playful headline per page (Instrument Serif)
     h2        page and section headings (Georgia)
     h3        card titles, the lead line (Georgia)
     body      paragraphs (Helvetica / Arial)
     small     labels, tags, buttons, meta (Helvetica, caps)

   SPACE: 8 · 16 · 24 · 48 · 96 (px)
   CORNERS: 999px for pills, 16px for cards
   SHADOW: one soft shadow, plus a slightly bigger one on hover
   BORDER: 1px ink
   COLOR: paper, ink, muted, plus one soft tint per page
