/* The 481-768px tablet band used to get a taller bottom offset here to dodge the
   calculator card vertically. That approach broke as soon as card content grew (it
   just traded one overlapping control for another — moving through the card instead
   of clearing it) and depended on exact content height, which is fragile. At 481-768px,
   public.css reserves extra right padding inside .calculator-card so the fixed launcher
   can sit over the card background without covering labels, controls, results, CTA or
   disclaimer — see the "Reserve an internal rail for the fixed support widget" rule
   there. No vertical offset trick needed here as a result; the widget uses its normal
   20/24px corner offset at every width. */

   Sized close to the artwork's own aspect ratio (~1.48) so object-fit: contain only

   teal (#0badba) so that sliver is invisible rather than showing the dark card color.
   static/images/support/support-robot.png was regenerated with a deliberate
   teal-matched margin around the robot (antenna/ears/mic all comfortably inside the
