/* Styles for the Elm-in-Elm editor (Editor.elm). The editor's markup uses these classes instead of
   inline styles; conditional state (the active file, the current gutter line, the live debug button,
   the current message chip) toggles an `active`/`current` class. A `[data-theme=dark]` block (driven
   by theme.js) darkens the light surfaces — the code editor, header and gutter are dark in both. */
