/* ==========================================================
   TAPPITRACK — SHARED INNER-PAGE SECTIONS
   Used by every page except the homepage. Class prefix: pg-
   Hero, in-page nav, feature grid, split, steps, tiles, FAQ,
   related links, CTA band, forms and product detail.
   Colours: brand blue, red, dark text, white and neutral greys only.
   ========================================================== */

/* ---------- Hero panel ----------
   Every inner page opens with a rounded colour panel: copy on the left,
   a framed screenshot or photo on the right (optional floating card).
   Tone classes pick a muted shade of the brand blue family from
   main.css; white text stays above WCAG AA contrast on all of them.
   The breadcrumb trail is not shown; BreadcrumbList structured data in
   each page's <head> gives search engines the page path. */
