   IGRAPHI Insights — light, institutional reading experience.
   Tokens mirror the main igraphi.com site (warm #f7f3ef background, ink
   #363a3e text, red #ED1C24 accent, Playfair Display headings, Inter body,
   Montserrat labels) so statically-served article pages are visually
   identical to the homepage's client-side Insights reader.
