docs(D.2b): roadmap — widget generalization (Plan 2) shipped

Record the D.2b widget-generalization landing: generic Type-registered widgets
built by DatWidgetFactory, thin find-by-id controllers, the ConsumesDatChildren
leaf rule, Type-3-not-registered decision, and the centered-UiText vitals numbers.
Both visual gates user-confirmed; 404 tests green.

 - **✓ SHIPPED — D.2b — Custom retail-look backend (Spec 1: markup engine + first panel).** Shipped 2026-06-14 (`626d06e`→`019350f`). Wired the dormant `UiHost`/`UiElement` tree into `GameWindow` (`ACDREAM_RETAIL_UI=1`) and built the **Approach-C markup engine**: `MarkupDocument` (XML → `UiElement` subtree, `{Binding}` reflection) + `ControlsIni` stylesheet loader + an `IUiRegistry` plugin UI surface (plugins ship markup + a binding, drained into the same `UiRoot`). First retail-faithful panel: a markup-driven Vitals window (`vitals.xml`) — 8-piece dat-sprite frame (`UiNineSlicePanel`) + three `UiMeter` bars (red/gold/blue + cur/max numbers) bound to `VitalsVM`, rendering live over the 3D world and coexisting with the ImGui devtools path. Retired divergence TS-30, added IA-15. Spec `docs/superpowers/specs/2026-06-14-d2b-retail-panel-frame-design.md`; plan `docs/superpowers/plans/2026-06-14-d2b-retail-panel-frame-plan.md`. NOTE the prove-out corrected two stale "facts": retail vitals are **bars not orbs**, stamina is **gold not cyan**. **Remaining: D.3 (AcFont — using the stb stopgap for now) + the glassy gradient bar sprite / brightness tune (polish); input integration (movable/clickable windows — the `UiRoot` drag/click machinery exists but isn't bridged to the Phase-K dispatcher yet); and the rest of the panels (D.5).**
 - **✓ SHIPPED — D.2b LayoutDesc importer (Plan 1 + default flip).** Plan 1 shipped 2026-06-15. *Retroactive registration — the spec requested this phase but it was not pre-registered before implementation.* Data-driven vitals window from `LayoutDesc 0x2100006C`: `LayoutImporter` resolves `BaseElement`/`BaseLayoutId` inheritance, walks the `ElementDesc` tree, and builds a live `UiElement` tree via `DatWidgetFactory` (Type 7 → `UiMeter`; all others → `UiDatElement` generic renderer). `VitalsController` binds live HP/Stamina/Mana by element id (mirrors retail `gmVitalsUI`). A/B visual gate **PASSED**: pixel-identical to the hand-authored window. **Default flip shipped 2026-06-15 (`bf77a23`):** the importer is now the default vitals window at `ACDREAM_RETAIL_UI=1`; the hand-authored `vitals.xml` and the `ACDREAM_RETAIL_UI_IMPORTER` flag were retired (`vitals.xml` recoverable from git history). The window is movable (Anchors=None + Draggable) AND horizontally resizable (Resizable/ResizeX, `8aa643f`): the dat edge-anchors reflow the pieces on width change per retail `UIElement::UpdateForParentSizeChange @0x00462640` (an earlier "fixed-size" note was wrong — inverted edge-flag reading, corrected; stretch is `RightEdge==1`). Faithful grip/dragbar-*driven* drag/resize INPUT is Plan 2. Post-flip number-render fixes (`43064ba`, `34243f2`): submission-order sprite draw (stamina/mana numbers had been overpainted by their own bars) + glyph pixel-snap (sharp at all resize widths). `MarkupDocument`/`UiNineSlicePanel` remain for the chat window + plugin panels. Spec: `docs/superpowers/specs/2026-06-15-layoutdesc-importer-design.md`; plan: `docs/superpowers/plans/2026-06-15-layoutdesc-importer.md`.
 - **✓ SHIPPED — D.2b LayoutDesc importer (Plan 2 — chat-window re-drive).** Shipped 2026-06-15. `GameWindow`'s hand-authored chat block (`UiNineSlicePanel` + inline `UiChatView`) replaced by `ChatWindowController.Bind(LayoutDesc 0x21000006, …)` — the same importer path as vitals. `ChatWindowController` places `UiChatView` (transcript) + `UiChatInput` (text entry + on-submit) + `UiChatScrollbar` (scrollbar thumb) + `UiChannelMenu` (channel selector) inside the dat-authored chrome; dead local statics `BuildRetailChatLines`/`RetailChatColor` deleted from `GameWindow` (moved into the controller). Wired to `_commandBus` (same `LiveCommandBus` as the ImGui `ChatPanel`) so type+Enter dispatches `SendChatCmd` server-ward. Transcript keyboard set from `_uiHost.Keyboard` for Ctrl+C/Ctrl+A. 392 tests green. Added divergence rows AD-28 / AP-38–40 / TS-30–31; updated IA-15.
+- **✓ SHIPPED — D.2b LayoutDesc importer (Plan 2 — widget generalization).** Shipped 2026-06-16 (`b7f7e2b`→`89626cd`). The hand-named chat widgets became GENERIC, Type-registered widgets built by `DatWidgetFactory` (`1→UiButton`, `6→UiMenu`, `7→UiMeter`, `11→UiScrollbar`, `12→UiText`); `UiField` (editable) ships controller-placed. `ChatWindowController` + `VitalsController` collapsed to thin `gm*UI::PostInit`-style find-by-id binders — this is the reusable toolkit + assembly pattern the future inventory/vendor/spell-bar windows build on. New `UiElement.ConsumesDatChildren` leaf-widget rule: behavioral widgets reproduce their dat sub-elements procedurally, so the importer must not build their children (an invisible Menu label child was swallowing the button click → dropdown wouldn't open). **Type 3 deliberately NOT registered** → `UiField` (acdream's Type-3 elements are inert sprite-bearing chrome/containers → stay `UiDatElement`; a subagent's Type-3→`UiField` registration was reverted — it blanked the vitals bevel + masked the regression by weakening a test). The editable input resolves to Type 12 → controller-placed `UiField` (Variant B). Vitals numbers rewired to a centered `UiText` (Task 8) — `UiText.Centered` reuses the meter's former centering formula, pixel-identical. Both visual gates (chat + vitals) **user-confirmed**; 404 tests green; new `chat_21000006.json` golden fixture. Amended AP-37, narrowed AP-41, added AP-42. Spec/plan: `docs/superpowers/{specs,plans}/2026-06-16-d2b-widget-generalization*.md`.
 - **D.3 — AcFont from portal.dat.** Replace stb_truetype system font with retail `Font` DBObjs (`0x40000000..0x40000FFF`) baked from `RenderSurface` source sheets — see research slice 03 §4. Preserves retail visual identity. **(D.2b dependency — needs the custom renderer.)**
 - **✓ SHIPPED — D.4 — Dat sprites + 9-slice panel backgrounds.** Shipped 2026-06-14 with D.2b. `TextureCache.GetOrUploadRenderSurface(id, out w, out h)` decodes `RenderSurface` (`0x06xxxxxx`) **directly** (not via the Surface→SurfaceTexture chain — the prove-out finding) → GL `Texture2D`; `DrawSprite` (explicit UV-rect, per-texture batch) added to `TextRenderer` + `UiRenderContext` + a `uUseTexture=2` RGBA frag branch; `UiNineSlicePanel` composes the universal 8-piece bevel (corners `0x060074C3..C6`, edges `0x060074BF/C0/C1/C2`, center `0x06004CC2`). Remaining art polish: the glassy gradient bar fill sprite (D.2b polish).
 - **D.5 — Core panels.** Attributes (`chunk_00470000.c:FUN_0047ba70`), Skills (same), Paperdoll (`chunk_004A0000.c:FUN_004A5200`), Inventory, Spellbook (`chunk_004C0000.c`), Fellowship, Allegiance. Each uses the port sketches in slice 05. **(Targets `AcDream.UI.Abstractions` — ships with D.2a using ImGui-rendered widgets; reskinned by D.2b.)** The *chat* panel originally listed under D.5 shipped early in Phase I (I.4 input + I.7 combat translator superseded the chat-panel design here); this entry now covers Attributes / Skills / Paperdoll / Inventory / Spellbook / Fellowship / Allegiance only.
