/* ============================================================
   CONTACT + FOOTER — scoped stylesheet
   Shared infrastructure (design tokens, .wrap, section.section,
   .reveal/.in-view) already lives in base.css. The duplicate
   [data-theme="dark"] block, *{box-sizing}, html/body/body rules,
   and .wrap/section.section/.reveal were stripped from the original
   delivery — all matched base.css already except --teal.

   --teal here (#2dd4bf dark) is the "majority" value shared by
   Capabilities/Experience/Projects, not Philosophy's (#0e7490/
   #22d3ee) that base.css uses globally — same three-way situation
   as those sections. Scoped below to #contact.cf-section, .cf-top-btn,
   and footer.footer TOGETHER, since the back-to-top button and the
   footer are DOM siblings of #contact, not descendants — a scope on
   #contact alone wouldn't reach them, and all three actually use
   --teal (the CTA ring's conic-gradient trim, contact-bar/footer-link
   hover states, and the back-to-top button's focus ring).
