/* ============================================================
   FAQ accordion - shared styling
   ============================================================

   The +/- question list used on the SREC, Geothermal REC, DIY sales and
   GREC calculator pages. Moved here verbatim from srec-faq.css so a page can
   have the FAQ without the rest of that file's page layout.

   Colours come from the --fe-* tokens in styles.css; the geothermal pages
   swap them for the olive palette. Link it straight after srec-faq.css on
   pages that load both, which keeps the cascade order it always had.

   Pairs with js/faq-accordion.js.
