   Deep Dives pillar — archive + small bits of article chrome.
   Self-contained / additive: this file only adds .dd-* selectors
   (and .pill-deepdive / .cta-ghost helpers used by the renderer).
   Loaded as its own versioned <link> so it never collides with
   collection.css. Uses the site's existing CSS variables.
