   Agent Brief

   Category: enhancement
   Summary: Add a News & Updates section to the Blazor web app home page that safely renders the repository's Markdown news feed with a graceful fallback.

   Current behavior:
   The MAUI app home page includes a News & Updates section backed by INewsFeedService / NewsFeedService, which fetches the repository's news.md Markdown feed, resolves relative assets/ image references, converts Markdown to HTML using Markdig with raw HTML disabled, sanitizes URL attributes, and falls back to <p>Welcome to NoteBookmark! Check back here for product updates.</p> if the feed is unavailable. The Blazor web app home page (/) currently displays only the static welcome card, feature overview cards, and technology badges, with no News & Updates section.

   Desired behavior:

   • The Blazor web app home page (/) displays a News & Updates section styled consistently with the existing Fluent UI layout.
   • The section loads and renders the Markdown news feed (docs/news.md, e.g. from https://raw.githubusercontent.com/fboucher/NoteBookmark/v-next/docs/news.md), resolving any relative assets/ image URLs so images render properly in the web app.
   • Markdown-to-HTML conversion uses Markdig with DisableHtml() and URL scheme sanitization (http, https, mailto for href, and safe image sources for src), preventing unsafe HTML or script injection.
   • Common Markdown parsing, asset URL resolution, and HTML sanitization logic can be shared between the MAUI app and Blazor web app if appropriate to avoid duplication.
   • If fetching or reading the news feed fails for any reason, the home page does not throw or break rendering, and instead displays the friendly fallback message (Welcome to NoteBookmark! Check back here for product updates.).

   Key interfaces:

   • INewsFeedService (GetHtmlAsync(), RefreshAsync(), FeedUpdated) and NewsFeedService — existing news feed contract and implementation in the MAUI app; can be adapted, shared, or implemented for the Blazor web app DI container.
   • Blazor Home page component (@page "/") — renders the News & Updates section within the Fluent UI layout.
   • Markdig MarkdownPipeline (DisableHtml()) and HTML attribute sanitization logic — ensures only safe href/src URLs are emitted in the rendered MarkupString.

   Acceptance criteria:

   • Visiting the Blazor web app home page (/) renders a News & Updates section styled consistently with the Fluent UI page layout.
   • Markdown content from the news feed (including links and relative images under assets/) is converted to HTML with raw HTML disabled and URL attributes sanitized.
   • Relative assets/ image paths (excluding path traversal segments like ..) are resolved so images display properly in the browser.
   • When the news feed cannot be fetched or read (e.g., network failure or non-success HTTP response), the section gracefully displays <p>Welcome to NoteBookmark! Check back here for product updates.</p> without throwing an unhandled exception.
   • Unit tests cover Markdown-to-HTML rendering, relative asset URL rewriting, URL sanitization, and fallback behavior on fetch failure.
   • Solution builds cleanly with nullable warnings treated as errors and all unit tests passing.

   Out of scope:

   • Changing the format or location of the upstream docs/news.md feed or docs/assets/ directory.
   • Redesigning the existing MAUI app home page or changing its offline file-sync workflow.
   • Adding an in-app editor or admin UI for publishing news items.
