Core.Portal.Chrome

Core.Portal.Chrome contains portal-safe MVC/Razor chrome primitives for product portals.

Owns

• Auth shell and form-alert components.
• Public auth split-shell template for MVC/Razor and Blazor portal hosts.
• Public and app header partials.
• Appearance controls and static chrome assets.
• Product-agnostic account-support view models and partials.

Does Not Own

• Product workflows, navigation trees, route maps, dashboards, tables, page copy, or customer/product behavior.
• Broker-backed sign-in orchestration. Use Core.Portal.SignIn for Core auth broker login.
• Persistence, database, API-controller, worker, database explorer, or product-repo dependencies.
• Product-specific API clients. Any support client in this package must call product-agnostic Core endpoints only and must be optional for consuming hosts.

Consumer Rules

Product portals should consume this package through NuGet package flow. The product host owns branding, route placement, cookie settings, tenant configuration, typed product API clients, smoke tests, and architecture allowlists.

Public Auth Shell

Use PortalPublicAuthShell from Blazor hosts and the _PortalChromePublicAuthWordmark / _PortalChromePublicAuthBrandField partials from MVC or Razor Pages hosts. Link _content/Core.Portal.Chrome/css/portal-auth-shell.css and set product-owned CSS variables for brand color, gradients, and typography as needed. Core owns the responsive shell, form spacing, field sizing, and alert primitives; product hosts own the sign-in form, forgot-password behavior, provider posture, proof credentials, and page copy.
