 | D-70 | Rail + licks layout concept doc: (a) guitar ≤4 shapes with the selection rule (open + common movable, lowest-position-first — name it); (b) piano 4 voicings as a 2×2 grid of compact MiniPianos — pick the MiniPiano thumb scale that fits two side-by-side in the ~456px column interior and two rows within a sane row height, honest math; (c) all ▶ removed from the rail's guitar+piano cells AND the licks strip (name every removal site); (d) hidden-but-scrollable scrollbars — the mechanism (webkit ::-webkit-scrollbar thin + dark thumb, and Firefox scrollbar-width/color; overlay where supported) and WHERE it applies (the rail's overflow-y column, any inner scrollers); (e) licks: uniform card footprint (thumb size parity between LickCard and PianoLickCard) + the strip follows the global instrument (guitar→piano licks on PIANO; bass honest empty); (f) recompute the row heights + the 500px column budget with the new smaller cells; migration order with bounded L-70/L-71 scopes (keep them file-disjoint or serialize on JamGuide.jsx). No user gate: pick strongest, record rationale + ≥2 rejected alternatives | design | claimed | — | `docs/design/dashboard-polish.md` | every change specced with honest numbers; the 2×2 piano scale chosen + proven to fit; bounded impl scopes |
 | L-70 | Implement the voicings rail per D-70: guitar ≤4, 2×2 smaller piano, ▶ removed, dark hidden scrollbars | engineering | backlog | D-70 | `src/components/GlanceRail.jsx`, `src/components/VoicingBrowser.jsx`, `src/index.css` (scrollbar CSS) (+ per doc — re-lock at promotion) | rail matches the spec; no ▶; guitar ≤4; piano 2×2; scrollbars hidden+dark+functional; build + smoke green |
 | L-71 | Implement the licks strip per D-70: uniform card size, follow the global instrument (wire PianoLickCard), ▶ removed | engineering | backlog | D-70, L-70 | `src/components/JamGuide.jsx` (LicksStrip), `src/components/LickCard.jsx`, `src/components/PianoLickCard.jsx` (+ per doc — re-lock at promotion) | licks uniform; piano licks show under PIANO; no ▶; bass honest; build + smoke green |
-| D-72 | Same-style related-progressions design (user answer = reuse existing KB): decide the presentation — when a style is active, RelatedProgressions leads with same-style siblings reframed as "variations / sections to try in {style}" (labels/section framing that reads as bridge/chorus/variation without new content); how the active style is known (roulette seed carries it; live detection's match yields it — name the prop/source); whether cross-style entries stay as a secondary "other styles with these changes" section or are dropped when a style is locked; empty/edge states. Files disjoint from the rail/licks chain (RelatedProgressions.jsx only) → runs in PARALLEL | design | claimed | — | `docs/design/related-same-style.md` | presentation spec'd against the real RelatedProgressions/match.js; active-style source named; L-72 bounded |
-| L-72 | Implement D-72: RelatedProgressions leads with same-style variations when a style is active; reframed labels; cross-style demoted/dropped per the doc | engineering | backlog | D-72 | `src/components/RelatedProgressions.jsx` (+ match.js additive if needed — re-lock at promotion) | same-style-first when a style is locked; honest cross-style fallback; build + smoke green (the C-50 ranking pins may need re-derivation — coordinate) |

 > Sequencing: D-70 → L-70 → L-71 (serial on JamGuide.jsx), and D-72 → L-72 run fully in PARALLEL (RelatedProgressions.jsx is disjoint). C-70 closes. Critic gates every task.
