/* ===================================================================
   Additions to Denys's v3 stylesheet.

   Everything above this line is his file, unchanged, so a later
   revision from him can be dropped in and these rules re-appended.

   What is new here is the styling for the blocks the live homepage
   actually has — the article list, the screener and webinar tables,
   the promotional banners and the video thumbnails — plus the header
   actions and the publications cards. All of it reuses his variables
   so the page stays one palette.

   Motion.

   Kept to three ideas so the page moves as one thing rather than
   twitching in six directions: content rises as it comes into view,
   the hero assembles itself once on load, and the two decorative
   pieces — the orbit and the tape — drift continuously.

   Everything here is switched off under prefers-reduced-motion. That
   is not politeness: for some people this kind of movement causes
   nausea, and a research site is read for a long time.
