Build the complete application in this repository. Work autonomously from start to finish and stop only when the app is complete.
If a minor detail is not specified, choose a reasonable solution and document it. Replicate the observable user experience of the reference app exactly: page structure, visible copy (button labels, errors, headings, tooltips, states), and interactions (what happens, in what order, on every action). Do not replicate the reference app's visual design, CSS framework, icon set, or color palette — restyle every screen using this repository's own Postrboard design system instead. Do not copy the reference app's implementation or framework.
Reference app (source of truth for UX behavior and copy only, not visuals): the-urlist/blazor-static-web-apps at https://github.com/the-urlist/blazor-static-web-apps — see Client/Pages/*.razor and Client/Shared/*.razor for exact copy, layout structure, and interaction behavior. Ignore Client/wwwroot/css/app.css a
