Phase 8 — Resource Loading + Character Encoding + Real Page Loading#

Implement the about:blank special URL that produces an empty HTML document.

Requirements#

  • Recognize about:blank as a special URL scheme
  • When navigating to about:blank, create a minimal empty HTML document without any network fetch
  • The document should be: <!DOCTYPE html><html><head></head><body></body></html>
  • Set the document's character encoding to UTF-8
  • Set the origin appropriately (opaque origin for about:blank)
  • This should be the default document when the browser starts with no URL argument

Integration Points#

  • url crate: recognize about: scheme
  • browser crate: use as default document on startup
  • ResourceLoader: handle about:blank without network fetch

Acceptance Criteria#

  • about:blank produces a valid empty DOM tree
  • No network requests are made
  • Document has correct encoding (UTF-8)
  • Browser opens to about:blank when no URL is provided
  • No external dependencies, no unsafe
  • Unit test verifying DOM structure for about:blank

Dependencies#

Depends on: Resource loader (for integration), HTML parser (already complete)
