/* MIRASTACK brand for the articles. The articles are kept byte-identical (blog.test.mjs), so the brand is applied here:
   - type: the articles ask for Poppins; on this site that name resolves to the Oswald file (the site font), and --font-sans points at Oswald;
   - colour: every colour variable of each article is mapped to the site's neutral-black palette (see site.css :root), per theme.
   The article's own variable block (inline <style> in the head) has selectors of specificity 0,3,0 at most; every rule below has 0,4,0
   and comes later, so it wins in all four cases: light, system dark, toggle dark, toggle light. Heading case and button shape are
   set inside the shadow root by BRAND_CSS in blog.mjs. */
