/* Below this width the app is the single-column, fixed-bottom-button mobile

   a wider frame, and a two-pane layout — inputs on the left, a live output
   pane on the right that stays in view (position:sticky) while you edit.
   Each side is grouped into a single flex container that IS one grid cell,
   rather than giving every card its own grid-column — CSS Grid's default
   auto-placement advances one row per DOM item regardless of column, so
   interleaved single-item placement produces a staircase, not two aligned
   columns.
   This block must stay LAST in the file: at matching viewport widths it
   needs to win over the unconditional rules above it (e.g. .generate-bar's
   position:fixed) at equal specificity, and a media query alone doesn't
   grant priority — source order still decides ties. */
