/*
  app.css: the website's styles. Colours, fonts and spacing come from
  tokens.css (generated from design/tokens.json): nothing here names a colour.

  THE IDEA
  --------
  An aeronautical chart: cool chart paper, navy ink, chart magenta for the one
  thing that matters on the page (a rarity, the primary action), and a dark
  caption strip under every photo like a printed plate. Dark mode is the same
  chart at night, not an inverted page.

  LAYOUT
  ------
  header     brand, live numbers, theme button; in a private copy, the census
             and test controls under it
  tabs       Types · Operators · Registered in · Favourites · Bounty · About
             (· Reports · Checks in a private copy)
  layout     left: the list (types, operators or search results)
             right: the routed page (type, operator, aircraft, bounty, ...)
  footer     credits

  The card grid is 3 across on a PC, 2 on a tablet, 1 on a phone. On a phone the
  header doesn't stay pinned (it took half the screen), and opening a page
  scrolls to it.
