/* ========================================================================
   ob-news-card.css : THE news card of the public site (operator 2026-09-25).

   ONE layout everywhere a news card appears : the /blog index grid, the news
   strip of every landing (home, /platform, /academic) and the "Articles for
   you" / related-articles section (blog article pages). The reference is the
   /blog index card : thumbnail, category eyebrow, jurisdiction flag, title,
   2-line blurb, date + read time, 14px radius, dark hover.

   Markup lives in ONE place per render path :
     server : templates/partials/landing/news-card.html (macro news_card)
     client : static/js/ob-news-card.js (ObNewsCard.html, same markup)
   Never restyle a card from a page : change it here or nowhere.

   Self-contained on purpose : the blog pages do not load landing-v3.css, so
   everything below relies on design-tokens.css only.
   ======================================================================== */

/* Radius : the landing v4 card radius (.lv4-about-card, .landing-card family).
   The floor keeps it at 14px while --radius-lg still carries its legacy 4px
   value in design-tokens.css, and follows the token up once it grows. */
