   of the old two-line 64px cell, and the retired capsule's 88px bottom gutter is
   gone too, so roughly 1.5× as many sessions fit on the same phone screen. The
   row still slides left over a clipped 44px strip; Pin + Archive sit in a real
   slot at the right edge and stay 44px tap targets. touch-action stays pan-x
   pan-y: sessions.js claims only a leftward (or open-row) horizontal first move,
   so vertical list scroll and a right swipe back to Chat still belong to the
   browser and #pager. It is `manipulation` (not `auto`) because two rows are now
   only 44px apart: `auto` lets Chromium fold two quick taps on neighbouring rows
   into a double-tap-zoom gesture and swallow the second tap's click (measured in
   the harness: a lost tap every few rounds). `manipulation` keeps pan + pinch
   and removes the double-tap zoom, so every row tap always delivers its click.
   The relative-time label, running ring, amber needs-input dot, pin glyph and
   unread "New" mark are all still drawn — they moved onto the single line (see
