/* ============================================================
   NITRO RABBIT LABS — PRODUCT DETAIL PAGES
   Page-scoped styles for nitro-fleet-agents.html, nitro-mapper.html
   and nitro-security.html only.

   Link order on those pages:
     main.css (tokens + base) -> site.css (components) -> product-page.css

   Nothing here restyles a shared component globally: every rule is
   either a new class or scoped under .product, so the rest of the
   site is untouched. All colour comes from the tokens in main.css.
