  The editorial template's styles: synthseo.ai's blog (Tailwind in the marketing site) as hand-written, mobile-first CSS.
  WHY: spec §6.4: pages must look like synthseo.ai/blog with no Tailwind runtime and no JavaScript; colours and fonts come from
    each site's settings as custom properties on <html> (render/views.py style_vars).
  RELEVANT FILES: ../base.html, ../list.html, ../post.html, skydera_grp_marketing_sites/synthseo/marketing/src/styles/index.css
