   Nomi Share — styles
   --------------------------------------------------------------------------
   Independent web app styles for the /share workspace overview. Token blocks
   are copied verbatim from css/styles.css (:root + [data-theme="dark"]) so the
   share view matches the main product exactly. Component styles below are
   share-specific. No colors are hard-coded — everything reads from tokens.
