/* ============================================================
   Overview scoreboard, charts, timeline, project register, task table.
   Charts are inline SVG built by charts.js. The security policy forbids inline style="" attributes, so every colour
   comes from a class here and every size from an SVG attribute. Marks follow the dataviz guidance: thin marks, a 2px
   gap between adjacent fills, recessive grid, labels in text ink (never the series colour), no text on status fills.
