/* =========================================================================
   Google Docs Dark Mode — landing page styles
   Design concept: "Midnight Desk" — a warm, literary dark theme (deep ink
   background, paper-cream accents, a single amber "reading-lamp" accent
   colour) built around one centerpiece: a fake Google Docs window you can
   flip between light and dark. Display type is a soft variable serif
   (Fraunces) to evoke ink-on-paper; UI/body type is Work Sans; small
   labels use IBM Plex Mono for a "editor chrome" feel.
