Elevate public site UX: premium hero, motion, scrollspy, shared footer

Redesign-preserve pass on the light editorial theme (dials 7/5/3):

- Hero: live availability status, accent value-prop, role line, social row,
  staggered entrance
- Motion (all motivated, reduced-motion safe): CSS scroll-driven reading
  progress bar, scrollspy nav with animated underline, CTA/blog arrow nudges,
  service hover accent rule, portfolio cover scale, card lift
- Shared multi-column footer across home + blog (brand, nav, contact, social)
- Fix anchor scroll offset under the fixed navbar (scroll-margin-top)
- Wire real social: LinkedIn, Instagram, email (code.soroush@gmail.com)
