/* ---------------------------------------------------------------------------
   Theme tokens. The app is dark-native: `:root` below IS the dark palette and its
   values are byte-identical to the pre-theme stylesheet, so the dark rendering is
   unchanged. The light palette is defined ONCE (--light-* block) and switched on in
   two places: an explicit `data-theme="light"` (menu 보기 > 테마, persisted in
   localStorage `dt.theme`) and `prefers-color-scheme: light` when no explicit choice
   was made. `data-theme="dark"` always wins over the media query.
   Canvas plots (scopes, snapshot, Δt map, 3D views) keep a DARK plot surface in both
   themes — their text/axis colours are drawn in JS by charts.js/arrayViz.js/three.js;
   `--plot-bg` is transparent in dark (identical to before) and dark in light.  */
