/* BienVu, le blog.

 * Linked from the head of /blog and /blog/<slug>, after the tokens and base rules of
 * styles.css have been defined but BEFORE styles.css itself in the page: the head slot
 * of Base.astro comes first. Every rule therefore starts from `.blog`, so it outweighs
 * the site rule of the same kind whatever the order. Accessibility helpers such as
 * .sr-only live in styles.css and are not redefined here.
