When the loop matches a KB style (rolled or live-detected),
RelatedProgressions leads with that style's other progressions under a
"Try these in {style}" header, labelled by data-derived character
(minor version / shorter form / extended form / reharmonized) computed
from mode/bars/qualities — no cross-style jumping. The role phrase is
suppressed unless the sibling is genuinely related (same changes or a
shared transition), so no false "variation" claim. When no style is
locked, today's cross-style list is preserved byte-for-byte. Smoke
893/893: §8 re-pinned (scores stable 92/156, labels moved) plus two
gate-added durable assertions (finding-B suppression + no-match
fallback). Critic PASS.

KB-sourced ranking per the one-screen spec: same canonical degree
shape +100 (with the mandatory collapse of consecutive equal
degree/quality pairs — a real detector-produced 12-bar fires its blues
relatives despite the raw-index matcher bug), same style +40, shared
transitions +12 capped 36, degree-set Jaccard, length penalty; floor
24, max 5, never padded; entries render name/style/level/annotation +
the chord chain realized in the live key as real buttons ->
ChordDetailModal. match.js: additive exports only. Ride-along: dead
currentChord prop dropped from the banner mount. Critic PASS (both
hand-verified scores recomputed independently; full entry lists
byte-matched on three scenarios; collapse counterfactual = 39).
