   The look introduced on the projects and home pages, in one place so every
   page stays consistent and a change here reaches the whole site.

   Load order matters. Always:

       <link rel="stylesheet" href="./css/style.css" />   <- site-wide legacy
       <link rel="stylesheet" href="./css/modern.css" />  <- this file
       <style> ...page-specific rules... </style>         <- page overrides

   style.css still owns the navigation and footer. Several rules below exist
   purely to undo its older, full-height-flex-centred page layout.
