/* ============================================================================
   The public landing page (landing.html).

   Standalone on purpose: styles.css is the whole app, seven thousand lines a
   first-time visitor has no use for. What is shared is the identity — the
   same self-hosted faces, the same warm paper and ink, the same highlight a
   comment leaves on a document — so the page someone signs in from and the
   app they land in are recognisably one product. The token values are the
   app's; keep them in step with :root in styles.css.

   The product pictures are drawn in HTML rather than screenshotted: they stay
   sharp at every density, follow the theme, reflow on a phone, and never show
   anybody's real documents.
