0.6.0

Fixed

• SummaryCard: Prevent layout shift during loading to data mode transition
  • Set explicit height on description skeleton wrapper to match description's rendered height
  • Normal mode: includes marginTop spacing (2px between lines)
  • Compact mode: accounts for webkit-line-clamp rendering difference (-2px adjustment)
  • Button skeleton width now matches actual button width for flat variant (auto-width 160px)
