# ZB.MOM.WW.Theme
Shared Technical-Light UI kit for the ZB.MOM.WW SCADA family: design tokens + IBM Plex
fonts (static web assets) and a canonical side-rail shell + widgets. The kit ships one
.NET 10 Razor Class Library (RCL) with CSS custom-property tokens, the three IBM Plex
woff2 fonts, and side-rail layout CSS — all served from `_content/ZB.MOM.WW.Theme/…`
plus a set of Blazor SSR components that carry no inline colours and reuse the token
classes. Bootstrap 5 is **not** vendored; each app keeps its own Bootstrap link.
## Adopt
1. Reference the NuGet package in your app; keep your own Bootstrap 5 `<link>` in `App.razor`.
2. In `App.razor` `<head>`, **after** your Bootstrap link, add `<ThemeHead />`:
```razor
<link rel="stylesheet" href="..." /> @* Bootstrap — yours, not vendored by the kit *@
<ThemeHead />
```
3. Make your `MainLayout` a thin delegate to `ThemeShell` — `@layout` cannot pass
parameters, so `ThemeShell` is a regular component and `MainLayout` is a 3-line wrapper:
```razor
@* Layouts/MainLayout.razor *@
@inherits LayoutComponentBase
<ThemeShell Product="OtOpcUa" Accent="#2f5fd0">
<Nav>
<NavRailSection Title="Navigation">
<NavRailItem Href="/" Text="Overview" Match="NavLinkMatch.All" />
<NavRailItem Href="/clusters" Text="Clusters" />
</NavRailSection>
</Nav>
<RailFooter>@* session info / sign-out link *@</RailFooter>
<ChildContent>@Body</ChildContent>
</ThemeShell>
```
Add `@using ZB.MOM.WW.Theme` to your `_Imports.razor` so all components are available
without per-file usings.
### Login page
Use `<LoginCard>` for the sign-in form. The card posts to a server endpoint
(`/auth/login` by default) so `SignInAsync` can run before the response starts.
You **must** inject `<AntiforgeryToken/>` inside the card and **validate `ReturnUrl`
server-side** before redirecting (open-redirect risk):
```razor
<LoginCard Product="OtOpcUa" Action="/auth/login" ReturnUrl="@safeReturnUrl" Error="@errorMsg">
<AntiforgeryToken />
</LoginCard>
```
## Components
| Component | Parameters (key) | Notes |
|---|---|---|
| `ThemeHead` | — | Emits `<link>` tags for `theme.css` and `layout.css`. Place in `<head>` after Bootstrap. |
| `ThemeShell` | `Product`*, `Accent`, `Logo`, `Nav`, `RailFooter`, `ChildContent` | Side-rail chassis. Not a layout — delegated to from `MainLayout`. `Accent` overrides `--accent` token. |
| `BrandBar` | `Product`*, `Logo` | Brand glyph + product name; rendered inside `ThemeShell`'s rail header. |
| `NavRailItem` | `Href`*, `Text`*, `Icon`, `Match` | Wraps `<NavLink class="rail-link">`. |
| `NavRailSection` | `Title`*, `Expanded` (default `true`), `ChildContent` | CSS-only collapsible `<details>` group; no JS, works in static SSR. |
| `StatusPill` (`StatusState`) | `State`* (`Ok`/`Warn`/`Bad`/`Idle`/`Info`), `ChildContent` | Inline chip. `StatusState` enum is in `ZB.MOM.WW.Theme`. |
| `LoginCard` | `Product`*, `Action` (default `/auth/login`), `ReturnUrl`, `Error`, `ChildContent` | Static form-POST sign-in card. Inject `<AntiforgeryToken/>` via `ChildContent`; validate `ReturnUrl` server-side. |
| `TechButton` (`ButtonVariant`) | `Variant` (`Primary`/`Secondary`/`Danger`/`Ghost`), `Type`, `Busy`, `ChildContent`, splatted attrs | `Busy` disables the button and shows a spinner. `ButtonVariant` enum is in `ZB.MOM.WW.Theme`. |
| `TechCard` | `Title`, `Header`, `ChildContent`, `Footer`, `Class` | Panel with optional head/body/footer slots. |
| `TechField` | `Label`*, `Hint`, `Error`, `ChildContent` | Form field wrapper with label, hint text, and inline error. |
\* `EditorRequired` parameter.
Flat namespace: all components and enums live in `ZB.MOM.WW.Theme`. One `@using` covers everything.
## Static assets
Served at `_content/ZB.MOM.WW.Theme/…` by the ASP.NET static-web-asset pipeline:
| Path | Contents |
|---|---|
| `css/theme.css` | Design tokens (`--accent`, `--ok`, `--warn`, …), typography, utility helpers |
| `css/layout.css` | Side-rail shell layout, collapsible nav, `StatusPill` variants, card/field helpers |
| `fonts/ibm-plex-sans-400.woff2` | IBM Plex Sans Regular |
| `fonts/ibm-plex-sans-600.woff2` | IBM Plex Sans SemiBold |
| `fonts/ibm-plex-mono-500.woff2` | IBM Plex Mono Medium |
`theme.css` declares `@font-face` with `url('../fonts/…')` — correct relative path from
`css/` to `fonts/`. (OtOpcUa's original `url('fonts/…')` was a latent 404; the kit fixes it.)
