/* CPDSE — Publications page (curated list of OpenAlex-sourced papers)
   ----------------------------------------------------------------------
   Designed to slot into the existing Jekyll site:
   - Site-wide :root tokens are reused (var(--green), var(--accent), …).
   - The page banner is rendered by _layouts/page.html (.page-hero).
   - Section breaks out of .page-body's 720px child clamp the same way
     the people page does — `width: 100vw; margin-left: calc(50% - 50vw)`
     paired with `overflow-x: clip` on html.                              */
