  /* Phones. The demo audience and the first-view moment both live here, so
     this is not an afterthought. The brand spec's two rules for a phone:
     TABLES BECOME STACKED CARDS below 640px -- never a horizontally scrolling
     table -- and CONTROLS GO TO A 44px MINIMUM.

     Stacked cards, mechanically: every cell becomes a block, the header row is
     hidden visually but kept for screen readers, and a cell that carries a
     data-label attribute prints it above its value. Two tables -- the home rows
     and a share's recipients -- are laid out as designed cards instead, with
     grid areas keyed on c-* classes, because "Recipients: dana@ +2" is not the
     row the canvas drew. The row menu survives the change: it is positioned to
     details.menu, not to the row.

     The first version of this block narrowed the cell gutter to 8px and hid
     columns, measured against a 412px table inside a 364px card. The stacked
     layout removes the reason; the gutters go back to being comfortable. */
