/* ═══════════════════════════════════════════════════════════════════════════
   /airplane-tracker/ — map chrome and aircraft sheet, in Pavlus colours.

   The behaviour (map.js, sheet.js, map-gestures.js) is copied verbatim from
   airplanetracker.com; only the paint is different. That site is a near-black
   instrument panel, this page is part of pavlus.com — cream, navy and gold, the
   same vocabulary as /ship-tracker/ — so every colour below is a restatement of
   an airplanetracker.com rule in this palette. If you change the markup in
   sheet.js, change it in both places.

   Palette is inherited from the page's own :root (--navy, --gold, --cream …),
   with fallbacks so this file is still legible if it is ever loaded alone.

   a time; an airliner crosses the popup's own width while you read it.
