The mood and medication-compliance heatmaps exposed per-day values only
through pointer tooltips. The cells now carry a visually-hidden day list
beside the grid — one entry per day that holds a value — so a screen
reader reaches the same figures without a tab stop per cell. A cell
subtree nested under the SVG's aggregate role=img is pruned from the
accessibility tree anyway, and a year-long grid would otherwise flood
the keyboard order; the rects stay a pure pointer affordance and the
aggregate summary label is unchanged. Tests pin the list and that the
cells carry no tab stops.
