GlassSection constructor
Creates a GlassSection with the required sliver content and header.
The sliver represents the scrollable body content, while the header
is the sticky element that gains a glass effect when pinned. This
constructor initializes the widget for use in sliver-based layouts,
ensuring the header adapts to pinned states and translucency from the
ArcaneTheme.
Implementation
const GlassSection({super.key, required this.sliver, required this.header});
