Dense ops table where rows above a heat threshold shimmer like air over asphalt — live DOM text refracts through an animated SVG displacement filter while cold rows sit dead-still behind hairline borders.
Use when a dense ops table where the rows needing attention should be findable by motion rather than by hue, hot rows refracting through a displacement filter while cold rows sit dead still; pick heatmap-calendar-tide instead when the magnitudes belong on a grid of time slots rather than in table rows, or meter-threshold-trip when one metric's trip and clear points are the question rather than which rows are hot.
