/* ============================================================
   FAQ hub — two-column category nav + Q&A panel

   Reference: callback.com's /v2/css/faq-page.css (same faq-layout /
   faq-sidebar / faq-cat / faq-entry structure). Recreated here using
   nsoftware.com's own brand variables (vars.css) and the visual
   conventions already used across the site (Open Sans Condensed
   headings, Segoe UI body copy, 2-4px radii, var(--link-color) for
   interactive accents) rather than Callback's blue/pill-shaped v2
   design language.
