   Seventh Planet — site stylesheet

   Components below are hand-ports of the design system's React sources in
   _ds_bundle.js (Button.jsx, Badge.jsx, Wordmark.jsx). Values are transcribed
   verbatim so the static site matches the design canvas. If the design system
   changes, re-derive these rules from the bundle rather than eyeballing them.
