/* Release notes (/changelog.html, DEC-WEB-24). Loaded after landing.css and built from its tokens: white canvas,
   near-black type, Soft Charcoal copy, the icon blue for the one download, 14 px controls and 20 px cards.
   Layout after vitalsmac.com/changelog: a large "What's new." heading, then one block per version, newest first,
   each bullet led by a New / Improved / Fixed label. Light only, like the landing page. */
