+The centered player avatar is also the touch movement handle. Its transparent
+target is 96 by 96 CSS pixels while the visible avatar can deflect at most 28
+CSS pixels. A 12-pixel dead zone and diagonal hysteresis resolve only cardinal
+intentions. Drag displacement selects a monotonically bounded local cadence
+from 360 ms to 170 ms, which remains slower than the authoritative 150 ms
+cooldown. The browser keeps one sent move in flight and coalesces all later
+drag changes into one latest intention; release discards that unsent intention.
+The deflection is local input feedback only. The maze redraws only after a
+server-authoritative projection and the browser never predicts a cell change.

 Commands use the version-one protocol envelope and contain intention data only:
