feat(ui): D.2b — toolbar collapse-to-one-row (bottom-edge snap resize hides/shows row 2)

UiElement.MaxHeight + ResizableEdges mask; UiCollapsibleFrame snaps height to the nearer
of {collapsed,expanded} and toggles row-2 visibility; GameWindow computes the two heights
from the layout + top-anchors the content. Amends IA-17. UiNineSlicePanel unsealed to
allow subclassing.

| IA-13 | GameEventType registry deliberately omits event types retail ignores; unknown events fall through unhandled | `src/AcDream.Core.Net/Messages/GameEventType.cs:11` | Retail also ignores them — dropping matches retail by construction | If the "retail ignores X" judgment is wrong for any opcode (or a server mod uses one), the event is silently dropped with no diagnostic pointing at the omission | retail GameEvent dispatch (ignored-event set) |
| IA-14 | Rendering + dat-handling base is WorldBuilder's tested port, not a fresh retail-decomp port (Phase N.4/O design stance) | `docs/architecture/worldbuilder-inventory.md` (code at `src/AcDream.{Core,App}/Rendering/Wb/`) | WB visually verified on the AC world, MIT, same stack; known WB↔retail deltas resolved case-by-case — terrain split kept retail `FSplitNESW` (**#51**, pinned by `SplitFormulaDivergenceTest`), scenery drift accepted (AP-31) | A WB-upstream divergence not yet caught ships silently as "our" behavior; guard = the inventory doc's 🟢/🔴 split + per-formula divergence tests | retail decomp per algorithm; `tests/.../SplitFormulaDivergenceTest.cs` |
| IA-15 | D.2b retail UI is our own UiHost/UiElement retained-mode tree drawing dat-sprite window frames, not a byte-port of keystone.dll's LayoutDesc binary tree. Both the vitals window (`LayoutDesc 0x2100006C`) and the chat window (`LayoutDesc 0x21000006`) are rendered by the LayoutDesc importer; `UiNineSlicePanel`/`RetailChromeSprites` now back only plugin panels | `src/AcDream.App/UI/Layout/LayoutImporter.cs` (vitals + chat) + `src/AcDream.App/UI/Layout/ChatWindowController.cs` | keystone.dll has no PDB/decomp so a byte-port is impossible by definition; we mirror retail's ElementDesc field model + controls.ini tokens, and the chrome sprites ARE the real dat RenderSurfaces (Step-0 prove-out 2026-06-14 confirmed 0x06004CC2 center + 0x060074BF..C6 bevel). The 8-piece edge/corner→position mapping is DATA-DRIVEN from the dat: the `LayoutImporter` reads `LayoutDesc 0x2100006C`/`0x21000006` and resolves chrome element positions + sprite ids directly from parsed dat fields; vitals locked by the conformance fixture `tests/AcDream.App.Tests/UI/Layout/fixtures/vitals_2100006C.json` | Remaining residual risk: anchor resolution at non-800×600 and the controls.ini cascade still lack an oracle — layout scaling at non-reference resolution and stylesheet token inheritance differ silently | `LayoutDesc 0x2100006C`/`0x21000006` (SHIPPED); `docs/research/2026-06-15-layoutdesc-format.md`; controls.ini tokens; keystone.dll layout eval (no PDB) |
| IA-17 | Toolbar window FRAME is toolkit-supplied (per-window UiNineSlicePanel 8-piece bevel, drawn over content via UiElement.OnDrawAfterChildren) rather than the window-manager-owned chrome retail paints uniformly around every window | `src/AcDream.App/Rendering/GameWindow.cs` (toolbar mount) + `src/AcDream.App/UI/UiNineSlicePanel.cs` | LayoutDesc 0x21000016 has NO baked frame; retail's toolbar frame is window-manager chrome (keystone.dll). We draw the same reusable 8-piece bevel chat/vitals use; border drawn over content so the toolbar's 2px-wide row-2 right cap (W=8) can't poke through. Same pattern as the chat window. | Until a central window manager owns chrome uniformly, per-window wraps can drift (size/offset/z-order) from each other and from retail; the border-over-content rule is the toolkit's, not the WM's | gmToolbarUI WM chrome (keystone.dll, no PDB); no bevel ids in LayoutDesc 0x21000016 (toolbar dump) |
| IA-17 | Toolbar window FRAME is toolkit-supplied (per-window UiNineSlicePanel 8-piece bevel, drawn over content via UiElement.OnDrawAfterChildren) rather than the window-manager-owned chrome retail paints uniformly around every window. It also supports a toolkit-defined collapse-to-one-row (bottom-edge resize snapping between a row-1-only and a two-row height, row-2 visibility tied to the stop) — retail's real collapse is keystone.dll (no decomp) and the dat stacks both rows always. | `src/AcDream.App/Rendering/GameWindow.cs` (toolbar mount) + `src/AcDream.App/UI/UiNineSlicePanel.cs` + `src/AcDream.App/UI/UiCollapsibleFrame.cs`; spec: `docs/superpowers/specs/2026-06-20-d2b-toolbar-collapse-design.md` | LayoutDesc 0x21000016 has NO baked frame; retail's toolbar frame is window-manager chrome (keystone.dll).

| IA-18 | Effect overlay tile (enum 0x10000005) is a `ReplaceColor` SURFACE SOURCE — pure-white pixels in the composited drag icon are replaced PER-PIXEL with the same (x,y) pixel of the effect tile (the SURFACE overload `SurfaceWindow::ReplaceColor` 0x004415b0), preserving the tile's texture/gradient; the tile itself is NOT blitted as an additional layer. This IS faithful retail behavior. **Anti-regression: do NOT re-implement this as a blit layer NOR as a flat-color replace (it is a per-pixel surface copy).** | `src/AcDream.App/UI/IconComposer.cs` (`ReplaceWhiteFromSurface`) | Faithful port of `IconData::RenderIcons` @407614 → the SURFACE overload `ReplaceColor` 0x004415b0 (`dst[x,y]=src[x,y]` where `dst==white`); confirmed via clean Ghidra decompile + named decomp + visual (the Energy Crystal's blue is a gradient, 2026-06-17). | A blit-layer or flat-color re-implementation would show the wrong effect look (no gradient) — the visual-verification regression that retired the mean-color approximation | `IconData::RenderIcons` acclient_2013_pseudo_c.txt:407524; `ReplaceColor` SURFACE overload 0x004415b0:71656; `docs/research/2026-06-17-stateful-icon-RESOLVED.md` |
