   cta-additions.css — conversion CTAs for the Articles section
   Link this AFTER /css/style.css, or paste these rules into style.css once.
   Purpose: give readers a prominent, repeated path to the course demos
   (/courses/) and plans (/pricing.html) so they don't get stuck in articles.
   Uses only existing design tokens, button classes and fonts.
