/* ==========================================================================
   Changelog page — "Changes in TwistedWave"
   Rendered through the "new" layout, so the design tokens from site-new.css
   (--accent, --ink, --border, --radius, --shadow-sm, …) are available here.
   Loaded on top of app-new.css; selectors are scoped under .changes and use
   two classes so they win over app-new.css's `.app-main h1/h2` rules.
