Use cases

  • Decorative enhancement

    Use shape() to add depth, masking, blending, or special treatment to supporting visuals.

  • Brand expression

    Apply effects where the interface benefits from stronger visual identity but still works in simpler environments.

Cautions

  • Heavy effects can hurt performance or readability on lower-end devices.
  • Do not use visual effects as the only way to communicate meaning or state.

Accessibility

  • Maintain text contrast and focus visibility when applying overlays, filters, or blend effects.
  • Visual polish should never reduce content legibility.
