/* ---------- Article pages, version 3 (28 Oct 2026) ----------
   Markup: renderArticle() in src/lib/article.mjs. Behaviour: article-page.js. Classes start ar-.
   The rules, from the research (clients/solarsave/pages/guide-solar-panel-grants/10-article-design-research.md):
   - Reading first: one column of about 70 characters, 19px near-black text at 1.65 (17px on phones). Nothing grey
     that people need to read; secondary text is --ink-soft, which is still 10:1 on white.
   - Structure comes from headings and white space, not boxes. One box on the page: the quote block.
   - Colour has jobs: ink for reading and links, orange for SolarSave's buttons only, and three status colours used
     only as words in the comparison table (green open, dark gold ending, grey closed; each over 6:1 on white). */
