   All presentation for the site. Mobile-first: the base rules are
   the phone layout, and media queries add the wider ones.

   Order of contents:
     1.  Tokens (the 5-colour palette) + reset
     2.  Typography primitives (.label, .tags, buttons)
     3.  The distance — fixed parallax ridges behind everything
     4.  The range — the fixed foreground mountain we walk on
     5.  The climber + his flags
     6.  Top bar
     7.  Hero / About / Milestones / Skills / Footer
     8.  Scroll-reveal + prefers-reduced-motion fallbacks
