   Shares brand tokens (--font-nav, --color-accent, --color-accent-deep,
   --color-navy, --color-description, --ease-out-quart, etc.) already
   defined in navbar.css; the --color-navy / --color-description /
   --color-accent-deep tokens (normally defined in features.css / hero.css,
   neither of which this page loads) are redeclared here so contact.html
   stays self-sufficient, following the same pattern used on blog.css and
   blog-detail.css.
