+  Add, configure, or review Ignite UI for Blazor Lite component support in Blazor applications.
+  USE FOR: installing IgniteUI.Blazor.Lite or IgniteUI.Blazor.GridLite,
+  registering AddIgniteUIBlazor() in Blazor Server, WASM, Hybrid, or split
+  Blazor Web App projects, adding @using IgniteUI.Blazor.Controls, wiring the
+  theme stylesheet and app.bundle.js assets, picking the right host page and
+  framework script, locating the GridLite stylesheet path, explaining
+  single-project vs split Server/Client Web App setup differences, and checking
+  where an interactive render mode is needed for Ignite UI components to work.
+  DO NOT USE FOR: general Blazor component authoring without Ignite UI, choosing
+  app architecture or render mode from scratch (see create-blazor-project),
+  JavaScript interop (see use-js-interop), authentication (see configure-auth),
+  prerendering (see support-prerendering), or layout/component design questions that need
+  no Ignite UI setup.
+---
+
+# Application Setup & Component Registration
+
+## 1. NuGet package
+
+```bash
+dotnet add package IgniteUI.Blazor.Lite       # OSS core UI components (MIT)
+dotnet add package IgniteUI.Blazor.GridLite   # OSS lightweight grid (MIT)
+```
+
+## 2. `IgniteUI.Blazor.Lite` Service Registration
+
+Usually in `Program.cs`:
+
+```csharp
+builder.Services.AddIgniteUIBlazor();   // all modules available
+```
+
+Pass `typeof(Igb<Name>Module)` values to eagerly pre-load a specific set instead:
+
+```csharp
+builder.Services.AddIgniteUIBlazor(
+    typeof(IgbInputModule), typeof(IgbComboModule), typeof(IgbDialogModule));
+```
+
+Module names always follow `Igb{ComponentName}Module`. In `IgniteUI.Blazor.Lite` a component registers its own module on first render, so the explicit list trims the initial payload rather than gating rendering.
+
+**Blazor Web App:** call `AddIgniteUIBlazor()` in **both** the server and the client `Program.cs`.
+
+```csharp
+// Server
+builder.Services.AddRazorComponents()
+    .AddInteractiveServerComponents()
+    .AddInteractiveWebAssemblyComponents();
+builder.Services.AddIgniteUIBlazor();
+
+// Client (WebAssemblyHostBuilder)
+builder.Services.AddIgniteUIBlazor();
+```
+
+## 3. `_Imports.razor`
+
+```razor
+@using IgniteUI.Blazor.Controls
+```
+
+Add it to both `_Imports.razor` files in split Blazor Web App solutions.
+
+## 4. Host page — CSS and script
+
+Host page is `wwwroot/index.html` (WASM/MAUI), `Pages/_Host.cshtml` (Server), or `Components/App.razor` (Web App).
+
+```html
+<link href="_content/IgniteUI.Blazor/themes/light/bootstrap.css" rel="stylesheet" />
+...
+<script src="_content/IgniteUI.Blazor/app.bundle.js"></script>
+<script src="_framework/blazor.web.js"></script>   <!-- or blazor.server.js / blazor.webassembly.js / blazor.webview.js -->
+```
+
+Both tags are required: without the stylesheet components render unstyled, without `app.bundle.js` they do not render at all. `app.bundle.js` must come **before** the Blazor framework script.
+
+Theme files under `_content/IgniteUI.Blazor/themes/` are `{light|dark}/{bootstrap|material|fluent|indigo}.css` — link exactly one.
+
+.NET 9+ Web App projects can use the fingerprinted asset collection:
+
+```razor
+<link rel="stylesheet" href="@Assets["_content/IgniteUI.Blazor/themes/light/bootstrap.css"]" />
+```
+
+`IgniteUI.Blazor.GridLite` ships its own stylesheet from its own asset root, but should be used only if you are using the GridLite component exclusively. If you are using other Ignite UI components, do not link (or suggest) the GridLite stylesheet — use the main theme stylesheet above instead.
+
+```html
+<link href="_content/IgniteUI.Blazor.GridLite/css/themes/light/bootstrap.css" rel="stylesheet" />
+```
+
+## 5. Render mode (Blazor Web App only)
+
+Ignite UI components need an interactive render mode; static SSR renders nothing usable.
+
+```razor
+@rendermode InteractiveServer   @* or InteractiveWebAssembly / InteractiveAuto *@
+```
+
+Or globally in `App.razor`: `<Routes @rendermode="InteractiveAuto" />`.
+
+## Project type reference
+
+| Project type | Builder | Host page | Framework script |
+|---|---|---|---|
+| Blazor Server | `WebApplication.CreateBuilder` | `Pages/_Host.cshtml` | `blazor.server.js` |
+| Blazor WASM | `WebAssemblyHostBuilder` | `wwwroot/index.html` | `blazor.webassembly.js` |

+  - name: Wire Ignite UI into a split Blazor Web App
+    prompt: |
+      I have a Blazor Web App with a separate Server project and Client project, and I want to use Ignite UI components throughout the app.
+
+      Please tell me exactly what I need to change to make that work. I need:
+
+      1. The package references for the core Ignite UI Blazor components and the GridLite package.
+      2. The service registration needed in Program.cs for a split Blazor Web App.
+      3. The _Imports.razor entry required so the component namespaces are available.
+      4. The host-page CSS and script tags, including the correct order.
+      5. Any note about where AddIgniteUIBlazor() has to be called in a split app.
+
+      Keep the answer concrete and file-oriented. I do not want a generic overview.

+      I have an existing Blazor Server app — one project, created from the original Blazor Server template, with Pages/_Host.cshtml as the host page.
+
+      I want to start using Ignite UI components (inputs, combos, a dialog) on a couple of my pages. Walk me through every file I have to touch and exactly what goes in it, in the order I should do it.
+
+      Also tell me whether there is anything about render modes I need to deal with here.

+  - name: Wire Ignite UI into a MAUI Blazor Hybrid app
+    prompt: |
+      I'm building a .NET MAUI Blazor Hybrid app — MauiProgram.cs, a BlazorWebView, and wwwroot/index.html — and I want to use Ignite UI Blazor components in the Razor pages it hosts.
+
+      I've tried this once already and got two different bad results: on one page the components showed up as plain unstyled markup, and on another nothing appeared at all.

+      - Does not send the user after render mode configuration, which does not apply to this project type
+  - name: Wire up a grid-only Ignite UI setup
+    prompt: |
+      I only need a data grid out of Ignite UI — none of the other components — so I added just the IgniteUI.Blazor.GridLite package to my Blazor WebAssembly app and put the grid component on a page.
+
+      I got a grid that was completely unstyled. My index.html currently has no Ignite UI tags in it at all.
+
+      Give me the exact package, startup and index.html changes for a grid-only setup, and don't have me pull in things I don't need.

+      - Keeps the setup grid-only instead of telling the user to also reference the full component package
+  - name: Set up Ignite UI components without the grid package
+    prompt: |
+      I have a standalone Blazor WebAssembly app — wwwroot/index.html, no server project — and I want to use Ignite UI inputs, a combo and a dialog on a few pages. I am never going to put a data grid in this app, so leave anything grid-related out of your answer entirely.
+
+      Two things I specifically want covered:
+
+      1. I want the dark material theme rather than the default one. Give me the exact stylesheet path.
+      2. My initial download is already big. Is there a way to pre-load only the modules for the components I actually use, and does that change whether the other components would still render?
+
+      Otherwise just give me the package, the startup registration, the imports and the exact index.html tags in the right order.
