Summary & Context

Aligns V3 typography with the Brands Foundation: trims Mona Sans VF and Monaspace to the supported weight/stretch ranges, removes the unused Space Mono typeface, drops legacy font-family fallback values, and applies letter-spacing / line-height / color fixes flagged from Component Staging Audit.

• Link to components/page: http://localhost:8000/v3/demo/components/

Changes

• Align Mona Sans VF and Monaspace font-face declarations with the design system in fonts.css
• Remove unused Space Mono typeface (font files, @font-face blocks, and references in typography.css)
• Remove fallback values from font-family declarations across V3 styles
• Apply typography review fixes across V3 components
• Fixed the missing whitespace in some dependencies mentioned in Dependency Card by querying the dependency's name (white-space preserved) instead of display_name_short.

Risks & Considerations

• The changes to the global font-stretch will cause all V3 pages to look different than before, which is expected, otherwise all of the changes should be low risk.
