plan: BLOCKBUSTER 767 — WIND THE KEY
The polish pass's design, appended to design/spec.md: hold Launch to wind the
key (three winds, an overwind red zone, boost fuel bought by the wind), the
aim shown as an elevation ladder and a throw arc, three named landmarks with a
called shot chosen on the launcher with Boost / Dive, an altitude tape against
the standing city, rounds that end when the city has settled, the Kid choosing
a line from what actually happened, and the screens seeing the room. The
decisions table's star thresholds now match the live 20k / 55k / 100k.
The two cross-slice contract files carry the interface every slice codes
against: rules gains the wind and landmark constants and the wind / callShot
events and puts the city's far edge where the layout always placed it;
game keeps its session, telemetry and bus in modules.state() so an edit no
longer wipes every subscriber, publishes the winding telemetry, and scores a
landmark and a called shot inside recordTopple.
