  PORTFOLIO STYLESHEET — Bennett Earle
  ============================================================================
  Design language: bold, high contrast, editorial.
  Syne (geometric, blocky) for display text.
  Mulish (humanist, readable) for body.

  Techniques:
    - CSS Grid masonry approximation for projects
    - CSS custom property animation (the grid art in hero)
    - :has() for smart parent targeting
    - CSS clip-path for the skill bar fill animation
    - scroll-driven animations using @keyframes + JS IntersectionObserver fallback
