/* ═══════════════════════════════════════════════════════════
   FAQ section — layout-agnostic base styles
   Loaded by baseof.html on any page where .Params.faq is set.
   Used by: blog/notebook, cert-tracker/single, video-single-content
   (cloud-labs + interview-prep both inherit from video partial).

   Notebook layout overrides these in zt-notebook.css with the
   handwritten/paper-feel chrome. Other layouts get the base look:
   clean prose typography with site-wide tokens.
