Orkuncakilkaya 31e6740033 feat(ludic.steps): chapters of steps, their kinds, progress and a party's pooled shares
A step is (kind, param, need) and a question about state: a kind has a
shape (yes, a count, a mask counted, every bit of a mask) and a pool
(world, any, sum, or, max, each), handed in by the game as StepsKind
records. An arc is chapters of up to STEPS_PER_CHAPTER steps; steps_check
sticks each met step of the current chapter (STEPS_MET) and opens the
next when all are (STEPS_CHAPTER), so a step met before its chapter
ticks at once. With company each seat's shares are held per chapter,
pooled as the kind says (steps_met, steps_party_got), counted for an
EACH step (steps_each, steps_lacking), and a leaver takes theirs along.

Port: StepsWorld { value(kind, param, player) (required), party,
present }. The package knows no kind's meaning and no chapter's words.

# check.ludic - once a frame on the machine that owns the story: every open step of the current
# chapter that is met now sticks (STEPS_MET), and a chapter with all of them done moves the arc on
# (STEPS_CHAPTER). A step asks about STATE, so one met before its chapter opened ticks at once.
