/* ---------- Side-by-side entry controls whenever height is the scarce

   Two triggers share the same row layout:

   1. A rotated phone/small tablet (`orientation: landscape` + a modest
      min-width to rule out odd narrow-portrait cases + a max-height cap so
      it doesn't fight rule 2 on a large desktop window). This is the case
      that matters most: pick the phone up in portrait and the pad sits
      below the board as normal; rotate it to landscape and the pad moves
      beside the board automatically, with no up/down scrolling needed to
      reach it — landscape phones are wide but short, so width is the
      dimension with room to spare.
   2. A generously sized desktop/tablet window (min-width AND min-height
      both large) — same side-by-side idea, just roomier sizing since
      neither dimension is under pressure there.

   Anything outside both — a portrait phone, a small or squarish window —
   keeps the default stacked layout above, where the pad below the board is
   never more than a short scroll away because the whole layout is compact
   to begin with. */
