/* ---- Desktop: sidebar case list + detail pane, side by side ----
   Pure CSS on top of the unchanged mobile layout/JS above — app.js still toggles the same
   .hidden classes via showScreen(); on mobile that's still one screen at a time (untouched
   behavior). At this width we override display on the cases/case screens specifically so both
   stay visible together, laid out as a two-column grid, once login is done. The `:has()` gate
   keeps the login screen a normal centered form instead of splitting into an empty grid before
   there's any case data to show. Not run in a real browser this session — verify on first use. */
