/* ── The split Studio (v5) ───────────────────────────────────────────────────
   Loaded LAST (after flow.css and home.css): it only adds to the single-page
   rules at the end of flow.css and to the landing screen of home.css.

   - .lp-steps            the step bar across the top (StepBar.tsx)
   - .lp-home--split      the empty Studio drawn as the same two panels
   - .lp-choice--split    the left panel: description under the images
   - .lp-flow-failure     a failed run, inside its own panel (FailureNotice)
   - .lp-flow-mobilebar   a phone's bottom bar repeating the current action
   Tokens only (lowpoly/base.css); no colour of its own. */
