docs(multi-bank): settle fork 5 — LICE tabs + both move affordances (Phase B closed)

5a: named-banks tab strip is LICE-drawn (matching M5 grid + Design View
segmented switch), with overflow/scroll in scope from B4 start.
5b: move ships as both a bindable "move to bank" menu and drag-between-regions;
copy stays the deliberate secondary act. Drag mis-drop mitigated by drop-target
highlighting and recoverable by design (index-only, reversible).

Phase B now fully settled (all five forks resolved), ready to scope into
implementation waves; only the active-bank indicator placement polish remains.

## Fork 5 — options for discussion, decision pending
## Fork 5 — settled (Daniel, 2026-07-23)
The one fork Daniel wants to weigh before deciding. Two sub-questions, both B4
panel-build mechanics, neither phase-defining but both shaping the panel's feel.
Nothing below is decided; the recommendations at the end are *pending Daniel's call*.
Two sub-questions, both B4 panel-build mechanics — neither phase-defining, both
shaping the panel's feel. The full options analysis that produced these calls is
retained below the decision for the record; the *decision* is what governs B4.
**Decision.**
- **5a — LICE-drawn custom tabs**, matching the M5 grid aesthetic and the Design View
`[ Arrange | Design ]` segmented-switch precedent. **Overflow/scroll is in scope from
the start** (chevron or scroll affordance), not deferred — a naive fixed-width LICE
strip breaks down at ~812 tabs, so the panel must scale from B4 onward.
- **5b — both a "move to bank" menu and drag-between-regions.** The menu is the precise,
MIDI-bindable front-end for the B3 move action; drag is the direct-manipulation
accelerator. Copy remains available as the deliberate secondary act, offered on the
menu. **Drag mis-drop is a designed-for property, not an afterthought:** the
destination region/tab shows clear drop-target highlighting during a drag, and because
move is index-only and move-is-default, a mis-drop is *recoverable* (the user moves the
sample back) rather than destructive — state this as the safety net, not a hope.
**Rationale (brief).** 5a: visual consistency across one coherent custom-drawn surface
plus full cross-platform certainty (we own every pixel, no SWELL tab-parity risk) beats
buying keyboard-nav/overflow from an inconsistent native widget; the segmented switch is
a partial precedent to extend. Overflow is pulled forward because banks routinely running
past a handful is plausible and a backfill after the naive strip ships would be a visible
cliff. 5b: the menu carries the precise/bindable path (and is the natural front-end for
the already-bindable B3 action, consistent with how the M5 grid and Design View act on
the current selection); drag serves users who prefer direct manipulation — the pattern
every media manager (Finder, Lightroom, Ableton browser) ships. The mis-drop hazard that
argued against drag-only is defused by highlighting + reversibility, so drag is safe as
the accelerator.
**Verify before building.** LICE tab drawing and any SWELL surface used for the
menu/drag hit-testing must be verified against the M5 reference and the SWELL/SDK headers
before use — even having chosen LICE, confirm what a native fallback would offer, and
confirm the drag hit-test doesn't collide with the M5 grid's existing multi-select drag.
