   Element defaults (reset, type, links, focus, forms) apply only inside an
   element with class "aces-v2", normally <body class="aces-v2">. A page opts
   in when it is redesigned in Phase 2; legacy pages can link this file and
   look exactly as before. Every scoped rule is wrapped in :where(), so it adds
   no specificity and any component or page class beats it.

   The u-* utility classes at the bottom work on any page.
