Detailed Description

Interactive preview of the user list banner art.

Renders the banner strip with the given CardArtParams through the same UserListPainter::drawCardArt() the live delegate uses, including the avatar placeholder and fade masks. Dragging pans the art vertically at output scale, the wheel zooms, arrow keys nudge, Backspace or Esc restores the parameters as of focus gain.
