Neon Cue v1.9.0 — Real physics & smart scoreboard

Real billiards physics, validated against textbook results on every build:

• Every ball has a full 3-D spin. It slides, then rolls at 5/7 of its speed after a centre-ball hit, just like real balls on cloth.
• Draw, follow and stun come from the real spin: the cue ball spins backwards while sliding forwards, then comes back.
• Throw: on a cut, ball-to-ball friction nudges the object ball 1–5° off the line of centres. It's larger on slow shots and smaller on fast ones (Alciatore's measured formula).
• Cushions grip a spinning ball, so right english sends it right and left english checks it.
• Verified: natural roll 0.714 (theory 5/7), sliding distance exactly matching theory, 90° rule 86°, 30° rule 33°, throw 2.4°, energy never increases, fully deterministic.

Exact aim line: the guide now plays your shot in the physics engine and draws the real paths:

• the cue ball to contact, the object ball (throw included), and the cue ball's path afterwards (draw and follow curves)
• where each ball stops, a green pocket when the ball drops, and a red SCRATCH warning

The ball goes exactly where the line shows. The cue's random stroke error is now an option that's off by default.

Smart scoreboard (Tab): frames or racks, score, current and best break, shots, pot success, fouls, live win chance for the frame and the match (based on the score, what's left, who's at the table and player skill), points left in snooker, and a match log. A win-chance bar also sits under the title.

The balls now visibly rotate with their true spin.
