Add `--screenshot <path>` to the UI Studio: when set the window is
created hidden (WindowOptions.IsVisible = false), the panel is loaded
and rendered into PanelFbo on the first OnRender tick, pixels are read
back with the new PanelFbo.ReadColorRgba(), rows are flipped (GL
bottom-left → PNG top-left), and the result is saved via ImageSharp
SaveAsPng before calling _window.Close().
Render size is derived from the loaded root's Width/Height (clamped
256–2048 px); falls back to 1280×720 when the root has no explicit
size. In headless mode ImGui, the inspector, and input wiring are
all skipped — only PanelFbo is created. Interactive path is
unchanged. SixLabors.ImageSharp 3.1.12 was already a direct dep of
AcDream.App (Phase O-T7); no new PackageReference needed.

Adds Task 4b: a second load path for the UI Studio that reads the committed
retail UI layout dump (docs/research/2026-06-25-retail-ui-layout-dump.json)
and renders any of the 26 retail windows as a static sprite hierarchy.
New files:
- src/AcDream.App/Studio/UiDumpModel.cs — POCOs + System.Text.Json parse of
the dump (UiDump, DumpPanel, DumpNode, DumpRect, DumpStateSet, DumpImage,
DumpState + UiDumpModel static helpers: Parse, ListSlugs, PickImageId).
- src/AcDream.App/Studio/DumpLayout.cs — DumpLayout.Load(path, slug, resolve,
out err): parses the dump, finds the panel by slug, builds a UiElement tree.
Internal DumpSpriteElement draws its sprite via DrawSprite (not reusing
UiDatElement — avoids the ElementInfo/StateMedia dat-import dependency for
this static mockup). DumpGroupElement is a transparent container for Group
nodes. Rect basis is ABSOLUTE in the dump (verified: inventory root at
absolute x=500 and its children also start at x≈500 — child offset from
parent is 0–50px, not 500px); DumpLayout subtracts parent rect to produce
parent-relative Left/Top for each child.
- tests/AcDream.App.Tests/Studio/DumpLayoutTests.cs — 5 tests covering:
inventory load with 0x100001D5 check + >= 40 nodes, unknown slug → null+err,
root at origin, children are parent-relative, all 26 slugs smoke-load.
Modified files:
- StudioOptions: adds DumpSlug + DumpFile fields; --dump <slug> and
--dump-file <path> args; ResolveDumpFile() walks up to the solution root
to find the default dump JSON (mirrors ConformanceDats.SolutionRoot()).
--dump suppresses the default vitals layout so the two modes are exclusive.
- StudioWindow.OnLoad: when DumpSlug is set, loads via DumpLayout (no
FixtureProvider, no controllers — static structure only); else falls
through to the existing LayoutSource + FixtureProvider path.
Results: DumpLayoutTests 5/5 passed; full AcDream.App.Tests 609 passed, 2
skipped (same as before); dotnet build green, 0 warnings.

Task 2 of the acdream UI Studio plan. Adds three new files under
src/AcDream.App/Studio/ and one new test file:
- StudioOptions.cs: record + Parse() for the ui-studio CLI args (positional
dat dir or ACDREAM_DAT_DIR, --layout 0xNNNN, --markup <path>; defaults to
vitals 0x2100006C when neither layout nor markup given).
- LayoutSource.cs: wraps LayoutImporter.Import for dat-backed layouts; markup
path sets LastError "markup unsupported (Task 6)" and returns null for now.
Exposes Kind / LayoutId / MarkupPath / LastError / CurrentLayout / Reload().
- StudioWindow.cs: Silk.NET 1280×720 GL 4.3 window; boots RenderBootstrap,
wires input to UiHost, loads the panel via LayoutSource, adds the root to
UiHost.Root.AddChild. QualitySettings resolved the same way GameWindow.Run()
does (SettingsStore → QualitySettings.From → WithEnvOverrides).
- Program.cs: ui-studio dispatch at the top of top-level statements (before
the dat-dir parse) so `dotnet run -- ui-studio` routes to StudioWindow.
- LayoutSourceTests.cs: dat-gated test (skips when dats absent); verifies that
the vitals LayoutDesc (0x2100006C) loads, root is non-null, byId contains the
vitals root element (0x100005F9), and Kind == DatLayout. Passes (1/1 with dats
present; silently skips on CI).
Note: the spec asserts FindElement(0x2100006Cu) — that id is the LayoutDesc
dat id, not a widget element id. The actual vitals root element id is 0x100005F9
(confirmed from the vitals_2100006C.json fixture). The test uses the correct
element id and documents the discrepancy.
