/* One screen, never scrolls. Height is rationed: bar, KPI strip, tabs (phone
   only), a grid that takes what is left, and a one-line footer. Every ancestor
   of a chart has min-height:0, or a grid row refuses to shrink and the page
   grows a scrollbar again. Chart colours are read from these tokens by app.js,
   so light and dark each have their own selected steps. */
