/*
 * The year in review. One slide per fact, full screen, and the sky moves from
 * dawn at the top to night at the bottom. Each sky carries its own ink: dark
 * on the bright skies, white from sunset on, chosen so every slide's text
 * clears 4.5:1 against both ends of its gradient (tests.js checks the pairs).
 * System fonts only; the site's CSP allows no others.
