Half-volleys: a rising ball is always scoopable; scoreboard tap shows the swing log

Field data (miss log) showed the dominant unfair miss: the assist parks
you on the landing spot, the ball spends the whole swing window below
minY rising off the bounce at your feet, and becomes hittable one frame
after the window closes. Root fix: the below-ankles rejection now only
applies to a DROPPING ball — rising post-bounce balls can be scooped at
any height (a half-volley). Feet-bounce taps go from ~0 to 19/30 winning
frames; 30 simulated real points now log 50 hits, 0 whiffs.

Also: swing-log snapshots record the same swing-timer value trySwing
tests (removes the one-frame misclassification behind 'unclassified'),
and tapping the scoreboard toggles an on-screen dump of the last 9 log
entries so live situations can be screenshotted from the phone.
