Credibility pass: the seams get sanded

Scoped to everything since the last pass (3308850). Three blind
reviews, every finding verified before touching anything.

Confirmed and fixed: two identical comment-splitting insertions left
doc comments orphaned from their fields (net and local alike); a
51-line CSS fossil of the pre-extraction inline effects survived in
Board.svelte; the rev-13 miss-roll test asserted tautologies while
its comment claimed a check the code never made — it now proves the
die was consumed, and the skeleton is no longer returned as trollId;
the sprite registry's `as never` silently disabled the completeness
its annotation advertised (now a mapped type, one cast at the
dispatch seam); a dead ternary guarded a union that doesn't exist;
Bolt carried a duplicate .fork rule from a color iteration; fxTtl
contradicted three sprites' real animation lengths; the permanence
sentinel was reinvented as a magic 9000 (the engine now exports
isPermanentDuration); CELL was declared thrice (fx.ts now imports
it); App and Replay ran two divergent fx schedulers (one scheduleFx
now, cancellable — stale flourishes can no longer fire after leaving
a game); TokenArt retried missing files forever; the anti-anti
escape guards merge with the gate asymmetry explained; wall-of-fire's
rev-12 carve-out is marked; overLimit ignored a displayed BRAINSTONE
(bots over-discarded by two); botRemark's header mis-stated its own
branches; deliverGold fired on any drop, not a home-base delivery;
escape and win banter never fired from the steps that carry them.

Rejected: "as a human would" (house voice); FxGallery's dev-harness
framing (trimmed one plea, kept the facts).
