/* ── Phone: the step buttons become a real 2-column grid ────────────────────
   What was wrong at 390px: `.yh-btns` is `margin-left:auto` + `flex-wrap`, so each
   wrapped row right-aligns to its OWN width and the stack comes out ragged, with a
   lone button on a row in places. It is also simply too tight — "USE A DIFFERENT
   PHOTO" at .72rem uppercase Oswald with .08em tracking needs about 172px, and half
   of a 390px row (less padding and gap) is about 175px.

   ⚠️ Checked on EVERY step, not just the first — the counts differ and a naive grid
   leaves a hole in some of them:
     step 1  4 buttons   Find / Use a different photo / Start over / Looks right
     step 2  3 buttons   Back / Use a different photo / Show my roof
     reveal  2 buttons   Adjust the outline / Use a different photo
   So the longest secondary (`#yh-auto`) takes a full row and the primary always
   spans the full width and lands last. That leaves no gaps at 4, 3 or 2 buttons,
   and puts the primary in the same place on every step. */
