Triage: always kill the body that would reach you first

The sequence drill tested nothing — the strip was always visible (no memory),
the batch was slow (no urgency), the aim was easy (no execution). A checklist
with gore, and Oliver said so: "not interesting enough to keep me playing".

Settled in discussion, he picked triage + streak. One rule: always kill the
body that would reach you first. Nothing is called, nothing shown — the court
is the puzzle. arrival = distance / speed down a held lane, and the roster's
speed spread means the answer is not the closest body: a runner at the far
baseline beats a roller at the service line. Court sense — and it trains the
exact target-priority read the gore mode rewards.

Wounds are free: only the kill is judged, so pre-softening a heavy while it
is third in line is legal and eventually necessary. The slack (0.9s) makes
near-ties legal both ways, or the rule is a coin flip. The streak is both
punishment and payout: x1..x5, a misread shows OUT OF TURN and resets it, and
nothing else happens — the queue keeps walking. Caught is the real setback.
Best score banks to localStorage; the world board can carry it if it ships.

drillMark draws a chevron over the queue head for playtest calibration. It
answers the exact question the mode asks, so it must be off in anything
shipped.

Deleted: the alphabet, the batch, the strip, the eaters. Shamblers are
first-class stream members with pts 20; a roller is 100.

30 tests, rewritten around arithmetic riggings (known speeds and distances)
instead of luck; 20 seeds clean.
