   Crumb — site stylesheet ("Midnight & crumbs")
   Colours come from the app icon: a navy night, a cookie moon, crumbs as stars.
   Paper is cool, never cream. Cookie is an accent for night surfaces and for
   space that has been found — never a background for chrome.
   Page-specific extras: /css/home.css (home only).
