-- Prosthesis types are assigned on the chart (`ProsthesisAssignChart` + `ProsthesisJobPopover` in `prosthesisTree.ts`). One **restoration** slot per tooth (crown / veneer-inlay-onlay-overlay); **screw-retained** is an implant add-on (`stackGroup: implant`, paints the crown) and stacks with a restoration. Implant abutments and post & core also stack (post & core stays off when the implant is screw-retained). Complete denture / overdenture / appliances / digital use **Upper arch / Lower arch** (`UA`/`LA`). **Partial denture** is tooth-level (select FDI teeth, Removable in the tooth picker); after send it is **one lab job** for all those teeth. Picker leaves are filtered by `chartRegion` so Removable appears in both tooth and arch pickers. Lab dispatch is on the same screen (no Treatment → Lab stepper).
+- Prosthesis types are assigned on the chart (`ProsthesisAssignChart` + `ProsthesisJobPopover` in `prosthesisTree.ts`). The picker is two columns (`4fr` wrapping category grid / `1fr` add-ons). Category tiles keep the wrapping `minmax(8rem, 1fr)` grid and stretch to fill the overlay; expanded children use that same wrapping grid with a parent-colored **L** rail (not a per-card tree). Empty crown suggestion: plus + dashed chip (`addonCrownCanBeAdded`) inside a full-height slot; after a crown is picked the slot stays as the filled type chip. Arch Upper/Lower/Both is a compact `h-8` segmented control at half the tree column width — it **is** the assignment (`retargetArchJobs`): Both→Upper/Lower drops the other jaw; Upper/Lower→Both copies the type onto the empty jaw; Upper↔Lower moves the job. Chart Upper/Lower arch labels are dashed outline buttons with plus (open the picker; control shows current jobs, or the clicked jaw if none). Category parents use the heaviest family pastel; children only lighten. One **restoration** per tooth (crown / veneer-inlay-onlay-overlay). **Screw-retained** is implant (`stackGroup: implant`, paints the crown) and is itself the restoration — no crown suggestion slot, and Crown / Indirect are disabled. Implant or post & core (without a non-crown restoration) shows a **crown** suggestion slot. A veneer/inlay/onlay/overlay hides the suggestion slot. **Post & core** category is visible but disabled when a restoration or implant is on the tooth. **Implant** category is disabled when post & core is on the tooth. Complete denture / overdenture / appliances / digital use **Upper arch / Lower arch** (`UA`/`LA`). **Partial denture** is tooth-level (select FDI teeth, Removable in the tooth picker); after send it is **one lab job** for all those teeth. Picker leaves are filtered by `chartRegion` so Removable appears in both tooth and arch pickers. Prosthesis FDI teeth **must** have jobs — never persist selected teeth without `toothProsthesis` (`pruneDetailTeethToJobs`). Catalog has no `addonKind` — stacking uses `stackGroup` plus the crown suggestion slot.
 - Detail chips show **type + teeth**, not “Detail N”. Lab-dependent chips use colored sent/unsent text (same size as the label); sent date stays on Lab dispatch.
 - Detail type may differ from appointment purpose. Purpose seeds the first line of an empty **appointment** draft (first open, and **Add detail** when the plan is `[]`). Later **Add detail** starts with an empty type. Unscheduled / New treatment still seeds a blank first line.
-- Lab shipments rail / “Go to dispatch” / load-with-focus **scrolls** to the dispatch panel (`pendingScrollToLabRef` + `labPanelRef`).
+- Lab shipments rail / “Go to dispatch” / load-with-focus **opens the dispatch view** in the chart slot (`pendingScrollToLabRef` + `labPanelRef`).
 - Live draft is **not** duplicated in the left rail preview; preview is for history browse only.

 Chart hit-testing (`FdiToothChart.tsx`): the hit target is the **unrotated full cell** (`pointerdown` + keyboard). Do **not** bind both `pointerdown` and `click` (double-toggle looks like a miss).
