   Loaded ONLY by blogs.html and blog/*.html.

   Every rule is scoped under .sfb (the page's <main>) or .sfb-progress —
   class names that exist nowhere else on the site — and none of the legacy
   blog classes from style.css (.blog-details-content, .course-price, …) are
   used any more, so this file needs no override hacks against style.css.

   Two site-wide rules it does have to neutralise, inside .sfb only:
     style.css   section { overflow: hidden }   -> would break position:sticky
     custom.css  h1 { text-transform: capitalize; font-size: 38px }
