/* AirwayControl Aircraft Library: page layout. Hand-written; build.py never touches it.
   Every colour is a palette token and every duration and curve a motion token in ds/tokens.css
   (docs/rules/01-motion.md). The drawings are the stars: they sit on a flat plate a step darker
   than the page, with air around them, and nothing competes with them for colour. */
