/*!
 * UMD Love Data Week -- Utilities gate (see js/umd-gate.js for the mechanism)
 * Self-contained: no dependency on this page's own CSS variables, since this
 * file is shared across the site-chrome tool pages and the bare standalone
 * app pages alike -- colors are written out literally below rather than as
 * var(...), so this never breaks on a page that doesn't define the same
 * custom properties docs.html/hub.html do.
 * Dark is still the base/default look (the values a rule starts with, same
 * as before this page had a light mode at all) with a :root:not(.dark)
 * override underneath each one for light mode -- the same interleaved
 * pattern .ldw-gate-banner below already uses. A bare standalone app page
 * that never loads js/main.js (so <html> never gets a `dark` class either
 * way) simply never matches the override and keeps the original all-dark
 * look, exactly as before. */
