   chat-share.css — the "Share chat" modal, the Usage Policy popup, and the
   public share-link viewer (a copy of a conversation rendered with the app's
   own chat styling).

   Owner surfaces (modal + policy) reuse the app's theme tokens so they track
   light/dark. The recipient viewer is self-contained: a stranger loads it with
   no stored theme, so every value has a literal fallback.
