/* ==========================================================================
   Accordion (HQDM standard, site-wide): FAQ items whose questions stay real headings
   (site.js turns them into buttons; content stays in the HTML for SEO / no-JS) and
   core Details blocks share one look: card per item, running number, accent edge when
   open, plus → minus icon, smooth open/close.
   FAQ markup contract (build.py emits it):
     .tr-faq            list wrapper (counter scope)
       .tr-faq__item    one Q/A
         .tr-faq__q     the old heading/paragraph, unchanged level and text
         .tr-faq__a     the answer blocks
