# A finger flick the shape Iris's phone delivers one, from
# docs/bench/iris-phone-v2-2026-09-06.md: at 120Hz a flick reaches the app
# as DOWN, one or two MOVEs and UP inside a few frames, with the
# intermediate positions batched inside those MOVEs as historical
# samples (~4ms apart, the touch digitiser's own rate) rather than
# arriving as separate events. Each line here is one such sample, which
# is exactly what `IrisViewPeer::on_touch_event` replays through the
# sensors one at a time -- so the whole gesture is 20ms and five
# samples, and the velocity has to come out of *those*.
#
# Downward (increasing y) on purpose: the screen opens pinned to the
# newest end, so a flick the other way has nothing left to scroll to and
# the fling clamps on its first tick -- a pass that would prove nothing.
# Coordinates are physical pixels on a 1080x2424 surface.
