/* The Coin Daily — editorial styling
   Cream-on-white "newsprint" aesthetic that mirrors the newsletter
   email template. Brand red #CF2224 used as the single accent across
   nav CTA, headlines, links-on-hover, and section meta labels.

   Visual model:
     - Page background: newsprint cream (#FCF1E6).
     - Content sits in white cards on the cream page (article, page,
       author, homepage hero).
     - Section meta labels: small-caps red, letter-spacing 0.08em —
       same pattern as "ALSO IN TODAY'S DIGEST" in the email.
     - Headlines: serif (Georgia), with a 3px × 60px red rule below
       on hero / article-page H1s — same brand mark as the email.
     - Article page: two-column above 1024px (body + "Also in today's
       digest" sidebar). Stacks below.
