Give him a sidestep, and split the messages into two voices

He died at every chapter boss because he could not move, and there were two
independent reasons for it. The movement block is 'rally'-only — a settled feel
decision the six boss AI styles were written around — and a boss is fought from
'pretoss'. On top of that canAimServe() is true through a boss fight, so his one
finger was already spent on the slingshot: there was no gesture left over that
could have meant "move".

So it is a SIDESTEP, not a walk. One committed step on a cooldown, carrying
invulnerability that beats both damage channels — the chip damage in hurtPlayer
and the instant-death contact test. The rule about walking stands untouched.

The gesture is picked by WHICH WAY the drag leaves the deadzone, decided once and
never revisited for that touch: down-ish is the pull the game already teaches,
sideways is the step. No timing window, no invisible mode, so "one gesture means
one thing" still holds. The finger-steer modes are untouched — stick.aimable is
false in a horde, so the drag is the absolute steer it always was. The apron demo
now alternates PULL DOWN and SWIPE TO DODGE, and Marvin has a page for it.

The rest of the playtest list:

- Bangers is bundled beside Silkscreen, and the register IS the category. The
  quiet face keeps the HUD, the rack, the control hints and RESUMING IN; the loud
  one takes SET, CHAPTER, EPIC!, PERFECT and every free-floating flash. Floating
  text gets one shared y and a drop shadow, so it survives crowd, clay and blood.
- Modals queue instead of being dropped. That was why the trainer and the weapon
  had to be crammed into one card after a won duel; the heal gets its own popup
  with the x_cross tin over it — a sprite loaded since that merge and drawn by
  nothing.
- weaponModal's first-sight gate moved inside the function. The barrels gated
  themselves and the tin ladder did not, so four weapons re-explained themselves
  every three games while a barrel weapon explained itself once.
- Ten rack slots. Past five it grows a second row upward rather than shrinking
  ten tiles under the thumb target; slots 0-4 stay welded to the bottom edge.
- The boss win holds for its own 3.6s and says EPIC!, with no GAME n NEXT line —
  the bar under the scoreboard already prints that permanently. That bar went
  from 6px to 7px, which is the smallest type in the game becoming words.
- The turn punches the camera in on him and the ground shakes harder at each beat.
