   Chrome for the multi-page site MVP — nav, footer, home page.

   EVERY selector is prefixed `mvp-`. The section blocks spliced in from
   landing.html carry their own inline styles plus a shared atomics sheet that
   already claims short class names (`.wrap` there means flex-wrap), so a bare
   element or generic class selector here would repaint them.
