   ABOUT PAGE — AmberNord
   Scope: .about-page-container and all children.
   Design language mirrors landing.css: spacing, border-radius, image
   treatment, typography scale, and CSS token usage.
   Depends on: main.css tokens — --color-gold, --color-bg, --color-text,
   --color-border-gold, --color-surface, --nav-height, --font-serif,
   --font-sans, --container-pad, --t-fast, --t-slow
