/* ==========================================================
   PetLinkTag — coming-soon homepage
   ----------------------------------------------------------
   Builds on app.css's color/type tokens but applies them
   differently here: a deep pine hero and footer bookend a
   calm paper-toned middle, instead of one flat tone top to
   bottom. The signature move is the tag itself — large,
   tappable, and literally the product idea in miniature.
