/* ==========================================================================
   RoboKit.ma — visual redesign v2
   ----------------------------------------------------------------------
   Robotics / futuristic SaaS theme: graphite-navy base, cyan "circuit"
   glow, copper kept as the warm accent (brand color — still referenced
   directly in HTML/JS via var(--copper-bright), so the name is kept).

   IMPORTANT: every selector and every CSS custom property name from the
   previous stylesheet still exists here. Nothing in HTML/JS needed to
   change — this file is a drop-in replacement for assets/css/style.css.
   ========================================================================== */
/* =========================================================
   728x90 AD BANNER — same approach as the KoooraLive site
   ---------------------------------------------------------
   assets/js/ads.js fills every <div class="ad-728-slot"></div>
   with an iframe. The slot is a full-width centered row; the inner
   box is locked to the banner's real size (728x90). On narrower
   screens `zoom` shrinks the WHOLE box (layout size included), so
   the banner is shown complete and no empty gap is left behind.
