/* editor.css — the BabelMe companion editor design system.
   Identity: the Transcribe family — near-black ink ground, one warm orange accent (spent on
   primary actions and human-edit marks), teal reserved strictly for live/link state.
   Document body is a real reading serif; UI chrome is quiet system sans.
   Themes: dark (default) and paper, via [data-theme] tokens. Print renders the document alone. */
