Build KPI metric cards with Tailwind CSS: a grid of tiles, each with a label, the current value, a delta chip, and a sparkline of eight to twelve vertical bars drawn with divs (heights as inline percentages, last bar in the accent color). No chart library, no SVG — pure CSS bars with rounded tops. Give the tile a hover lift and keep all sparklines the same height so the grid rhythm holds.
