CFPB Design System — complete local specimen

Implementation: Native CFPB 5.10.2 CSS and Expandable JavaScript; verbatim package base CSS extraction, system-font fallback, and original application content.

1. Extract this archive into its own directory.
2. Run: python3 -m http.server 8080
3. Open: http://localhost:8080/cfpb.html

The HTML includes the document root, layout/theme overrides and initialization.
Its relative vendor directory includes the actual CSS, JavaScript module chain,
fonts and other packaged assets used by this specimen. Preserve this structure;
ES modules require HTTP rather than opening a file:// URL.
