/* The blog and the pages written as articles (deploy/build-blog.mjs), and the homepage's "From the blog". Every rule is
   scoped to the blog's own elements (.post, .rail, .blog-head, .bcards…), so a page that loads this beside its own
   styles (the homepage, /compare) keeps its look. A reading column on the site's dark theme, the contents in a rail
   beside it that follows the reading, the crew cyan for links. */
