   Stylesheet: design system / token layer + structural scaffold
   -----------------------------------------------------------------------------
   This file is intentionally organised as:
     1. Design tokens      (CSS custom properties — the single source of truth)
     2. Reset / base
     3. Layout primitives  (container, section rhythm)
     4. Scaffold helpers    (visible placeholders for empty stub sections)
   Page-component styles are added later, on top of these tokens.
