/* =================================================================
   RDI Trials — base stylesheet for the "direction" rebuild.

   RECONSTRUCTED from the RDI design system (colors_and_type.css +
   ui_kits/marketing-site/kit.css) and the token set used inline across
   the mockup pages. This renders every page in the redesign/ folder so
   the site can be clicked through and reviewed.

   NOTE: This is a faithful, on-brand reconstruction, not the original
   production stylesheet. If you have the real assets/styles.css from the
   mockup export, drop it in here to get pixel-exact parity. Licensed Klim
   fonts (National 2 / Söhne Mono / Tiempos Headline) are NOT bundled;
   this file loads Instrument Sans + Instrument Serif as close, freely
   loadable stand-ins so nothing ships watermarked/licensed fonts.
