Credibility pass: session residue swept from the rev-10 run

War-story comments become timeless constraints (carrier rule, boobytrap
tell, remove-curse prescription); the rev changelog reunites under
GameConfig.deckRev; three hand-copied cardless stack literals fold into
openCardlessStack; the visionstone one-edge loop is shared via
throughOneEdge with the edge-target hairpin exclusion stated; drain()
moves to test helpers and replaces four inline copies; the butt-head
sweep test loses its dead scaffolding and its expect(refused || true)
tautology and now asserts both branches; a process-named suite is
renamed for the behavior it pins; dead .bezel-spacer CSS and the fx
effect's fossilized cleanup story go. No behavior changes: 304 engine
tests pass, 36/36 ledgers replay, web typecheck clean.
