/* ==========================================================================
   NR-BOS product tour — real screenshots, dedicated page (/work/nr-bos/).
   Loaded only on pageKey == "nrBos" (see base.njk). Namespaced under
   .nrb- so it can't collide with the rest of the site. Uses the site's
   real brand tokens (--navy/--gold/--paper/--muted/--border from
   styles.css) — no new palette introduced for this feature.
