-### Minimal Application
+### Application Startup
 
-```csharp
-// In App.xaml.cs — initialize theme before creating any UI
-FrameworkUI.ThemeManager.SetTheme(FrameworkUI.ThemeColor.Light);
+The shell requires an application-specific `FrameworkInterfaces.IProject` implementation and a concrete subclass of `FrameworkUI.FrameworkUIController`. The controller provides the project tree, menus, and document/property views; it is the value assigned to `MainWindow.ProjectNode`.
+
+Use this helper from your WPF application's `OnStartup` override or `Startup` handler, on the UI thread. Omit `StartupUri` in `App.xaml` so WPF does not create a second window. Supply a factory that creates your controller around an initialized project. The factory runs after theme initialization because controllers can construct WPF controls.
 
-// Create project and controller
-var project = new MyProject();
-var controller = new MyProjectController(project);
+```csharp
+public static class ShellStartup
+{
+    public static FrameworkUI.MainWindow Show(
+        System.Func<FrameworkUI.FrameworkUIController> createProjectNode)
+    {
+        FrameworkUI.ThemeManager.SetTheme(FrameworkUI.ThemeColor.Light);
+        FrameworkUI.FrameworkUIController projectNode = createProjectNode();
 
-// Show the main window
-var mainWindow = new FrameworkUI.MainWindow();
-mainWindow.ProjectNode = controller;
-mainWindow.Show();
+        var mainWindow = new FrameworkUI.MainWindow
+        {
+            ProjectNode = projectNode
+        };
+        System.Windows.Application.Current.MainWindow = mainWindow;
+        mainWindow.Show();
+        return mainWindow;
+    }
+}
 ```
 
-Run `FrameworkUI.Demo` for a complete working example.
+`Application.Current` and the application's resource dictionaries must already exist. Merge the icon and control dictionaries used by your views into `App.xaml`; see the working [demo resources](src/FrameworkUI.Demo/App.xaml). `MainWindow` restores the saved theme preference when it loads user settings, so that preference can override the initial Light theme.
+
+Run `FrameworkUI.Demo` for a complete application. Its [startup handler](src/FrameworkUI.Demo/App.xaml.cs), [project model](src/FrameworkUI.Demo/Model/DemoProject.cs), and [project controller](src/FrameworkUI.Demo/UI/DemoProjectNode.cs) show the host implementations and initialization order.

Use **Project > New Hazard Element...**, or right-click **Hazard Functions** and choose **New Hazard Element...**, to add a named sample hazard. Double-click the new element to open its document. Use the demo's distribution and property controls to display a meaningful example.
+
+Choose the theme under **Tools > Options > Application**. Keep the same window size, docking layout, selected document, and data for the Blue, Light, and Dark shell captures. Capture the hazard document in Blue with its chart and properties visible; its tabular results and parameter sets are separate tabs.
+
+The captured **Example Hazard** uses Log-Pearson Type III with mean (log) `3`, standard deviation (log) `0.5`, skew (log) `0`, effective record length `100`, and uncertainty enabled. These settings form an illustrative demo example.

+
+The uncertain curve and uncertain table captures share six illustrative Normal distributions entered through the demo UI: X values `[0, 2, 4, 6, 8, 10]`, means `[30, 24, 19, 15, 12, 10]`, and standard deviation `1` for every row. These are demonstration values, not measured data.
+
+On **Time Series**, select the built-in **Hourly** example: constant value `15`, beginning `1980-07-30`. The pictured data comes from the local Hourly example. The separate USGS option retrieves external data. On **Bivariate CDF**, select the **Plot** tab.

 ## DatabaseControls
 
 - `database-table-viewer-blue.png`
 
+Launch `DatabaseControls.Demo`, select Blue, and load the [synthetic sample CSV](samples/synthetic-gallery-sample.csv). The capture uses 12 fictional records with **Sample ID**, **Category**, **Value**, **Units**, and **Source** columns. Each row is labeled **Synthetic** and uses **example units**. These records demonstrate the table controls and are not observed measurements or production data. The demo starts without a loaded table.

+Launch `ExpressionParserControls.Demo`. This demo initializes Light and has no theme selector. Enter `((120 + 80) / 2) ^ 2` so the editor, operator controls, and evaluated result `10000` are visible. This standalone demo does not host the optional function browser.
 
 ## DAGControls
 
-- `dag-flowgraph-canvas-blue.png`
+- `dag-flowgraph-canvas.png`
+
+Launch `DAG.Demo` and retain its default appearance; it does not expose the framework theme selector. The canvas starts empty. Add sample nodes from the toolbar or canvas context menu and arrange them with room for their labels and input/output connectors. Capture the actual populated canvas.
+
+The demo's **Save** and **Load** handlers are placeholders and cannot save or open graph files. Connection creation is intended to use a drag from an output circle to an input circle, but this workflow was not verified for the gallery capture. The screenshot and caption therefore describe the visible nodes and connectors without claiming a successful connection.
 
 ## Capture Notes
 
-- Capture from the demo apps in `src/`.
-- Keep screenshots focused on the relevant control.
-- Prefer 1200-1600 px wide PNGs.
+The 18 new screenshots were captured on **2026-10-07** from Release demo builds at commit `05acb1e`. The four preexisting GenericControls images were retained. The new screenshots retain their native pixel resolution, with focused regions cropped from JPEG captures and saved as PNG.
+
+- Capture actual demo windows or focused control regions, with text readable at the gallery's displayed size.
+- Prefer 1200–1600 px wide PNGs for full windows when the display permits. Keep focused controls at their native resolution; do not upscale smaller captures.
+- Use the demos' bundled or initialized sample inputs where available. The database table is an explicitly synthetic gallery example.
+- Keep window dimensions and framing consistent within each group, especially the shell theme comparison.
+- Wait for layout and rendering to settle. Move the pointer away from the focal content and dismiss transient tooltips or unrelated dialogs.
 - Avoid local paths, personal data, debug windows, and unrelated desktop content.
+- Inspect every image for cropped labels, blank plots, selection artifacts, and unintended horizontal scrolling.
+- Verify that every image referenced by `docs/gallery.md` exists and that its theme matches its filename and alternative text.
