background with subtle radial gradient. Deep sage green and warm
terracotta accents. Stylized minimalist illustration of a server
rack with circuit lines and a health check pulse line going through
it. Modern clean tech aesthetic, no text overlay, balanced negative
space, soft drop shadows, 1200x630 horizontal format, looks like
a SaaS landing page hero image.
