/* ===== Chart sizing fix (prevents runaway growth) =====
   Chart.js is responsive by default. If the canvas height participates in layout
   and is also being set by JS, you can get a feedback loop where the canvas grows.
   We give the chart a fixed-height container and absolutely position the canvas
   inside it so the chart can never expand the page height.
