/* ==========================================================================
   NR-BOS interactive overview — launcher card + tabbed modal.
   Loaded only where the launcher appears (currently /work/nr-bos/ — see
   base.njk, pageKey == "nrBos"). Namespaced under .nrb2- (distinct from the
   .nrb- prefix already used by product-overview.css on the same page) so
   the two features can't collide.

   Uses the site's real brand tokens (--navy/--gold/--paper/--charcoal/
   --muted/--border/--font-serif from styles.css) plus a small set of new
   semantic status tokens this feature needs. Logical properties throughout
   so the whole thing mirrors correctly under dir="rtl" without a separate
   RTL stylesheet — the one exception is the before/after slider's
   clip-path, which has no logical form and is overridden explicitly for
   [dir="rtl"] below.
