Fix sparkline infinite-resize loop on experiments page (#7)

Chart.js with responsive+maintainAspectRatio:false needs a positioned, fixed-height parent to size against. Without it, canvas inherits the parent's auto height, Chart.js resizes the canvas, parent grows, canvas

Chart.js with responsive+maintainAspectRatio:false needs a positioned, fixed-height parent to size against. Without it, canvas inherits the parent's auto height, Chart.js resizes the canvas, parent grows, canvas resizes again — runaway loop that pushed cards off-screen.

Wrap each canvas in a position:relative, fixed-height div per the standard Chart.js recipe. Force canvas to 100% inside that wrapper.
