/* =====================================================================
   PinBoostr — /pinterest-and-linkedin/ ("the duo page").
   Loaded only by page-pinterest-and-linkedin.php. Prefix: .pbd-

   The page argues one thing: Pinterest and LinkedIn do opposite jobs. So
   the layout argues it too — everything is built as a pair. Two accents
   run the whole page (rose = Pinterest, blue = LinkedIn) and the page's
   set pieces are a lifespan chart and two timelines, not icon cards.

   Sits on the retro warm paper so it still reads as PinBoostr; no glow,
   no gradient text, no pill badges.
