/* ---------- Phones (layout fix) ----------
   Before: the composer squeezed the text box to ~120 px between the Live button and the language picker (placeholder wrapped on 3 lines),
   the live bar wrapped onto two rows, notes headings were huge, and iOS zoomed the page when a small select was tapped.
   Now: text box on its own full-width row, one compact action row under it, one-line live bar, calmer headings, safe-area padding. */
