wuwiandClaude Opus 5 e85345e0d8 Splatter: invert the aim camera, and make the pull's angle actually matter
The aim camera now drops and pushes IN while you draw instead of lifting and
leaning back — you crouch into the shot. Both knobs just flip sign, so the old
behaviour is a sign change away in the T panel.

And the reason the pull's angle felt like it did nothing: aimCone 0.45 meant a
lane half-width of ±10 m at the far baseline, which is the entire court. Every
downward pull locked the same body, so the indicator's angle was decoration.
At 0.10 (±2.9 m out there, ±0.9 m at your feet) the angle picks a lane for
real — swept in 4° steps against three shamblers 18 m out, each one owns a
~12° window and past ±20° the ball flies into an empty lane. Thumb-sized, but
you have to point.
