/* TobioEdge site shell. Shared by every project page and privacy page.
   This file owns the skeleton only: header, footer, store badges, phone
   frames, the reading layout for privacy pages, and the responsive rules for
   those parts. It never sets a colour or a font directly. Every value comes
   from the tokens the page defines in its own <style> block:

     --bg, --bg-alt, --panel, --border      surfaces
     --text, --muted, --dim                 type
     --accent, --accent-strong              links and highlights
     --display                              the display font stack

   Change this file and every page on the site changes with it, which is the
   point. Change a page's tokens and only that page changes. */
