   Rev2IT — custom-additions.css
   Adds: Services & Products nav dropdowns, needs-based service cards,
   and generated background art for product cards.

   No external images are used anywhere in this file. Every background
   is a CSS gradient and/or an inline SVG data-URI, which keeps this
   fully compliant with the page's existing CSP
   (img-src 'self' data:; style-src 'self').
   ===================================================================== */

   fixed nav bar.

/* ---------------------------------------------------------------------
   Nav dropdowns (Services / Products) — plain Bootstrap 5 markup
   (.dropdown / .dropdown-toggle / .dropdown-menu / .dropdown-item),
   restyled to match the site's dark theme.

   This block is written from scratch rather than relying on the full
   Bootstrap stylesheet, so nothing here can be silently missing from a
   compiled/purged CSS bundle, and it can't collide with the rest of
   the page's Tailwind classes. The Bootstrap dropdown is initialised
   with data-bs-display="static" in the HTML, so the JS never injects
   Popper's inline positioning styles — keeping this fully compliant
   with the page's style-src 'self' CSP.
