DsSurface class

A container that adopts a ColorScheme surface level as its background.

This is the foundational surface primitive of the design system. All layouts and card-like components should be built on top of DsSurface rather than hardcoding colors.

The color is sourced exclusively from Theme.of(context).colorScheme — no color is ever hardcoded.

DsSurface(
  level: SurfaceLevel.low,
  borderRadius: AppRadius.card,
  padding: AppSpacing.cardPadding,
  child: Text('Hello'),
