   UNICRON HOLDINGS — landing page
   Compiled from a Claude Design (.dc.html) document into a standalone static
   site. The Nequity design-system tokens the source referenced
   (--font-sans, --radius-pill, --shadow-lg) are inlined below; the design's
   runtime behaviors (style-hover / style-active / style-focus, the FAQ
   accordion, the request form) are reimplemented in plain CSS + assets/app.js.
   Webfonts (Hanken Grotesk + Cormorant Garamond) are loaded via <link> in
   index.html.
