   KENZLY — dark theme layer (Kenzly Design System, claude.ai/design
   project "Kenzly Design System", id 7a2da353-…-adbc2f2557bd).
   Monochrome / machined: near-black canvas, silver chrome text,
   hairline borders, flat elevation. Currently linked by index.html
   only — the future shared base once other pages adopt this
   direction. Values are copied from the DS's tokens/*.css and its
   ui_kits/website/*.jsx composition (which is the more concrete
   source where the two ever disagreed — e.g. the JSX composes
   sections with 32px gutters even though spacing.css lists 24px).
