// The contribution card on the dashboard (views/heatmap.rs). Cells are squares with a 3px gap;
// the grid lays out seven rows and fills columns, so a week is one column. Colours come from the
// --h0..--h4 tokens, so both themes follow main.scss.
//
// The cell size follows the card: 53 columns fill the card's width, between 11px (then the grid
// scrolls inside the card) and 16px. The card is a size container, so 100cqi is its width.
