/* Operations dashboard, first screen. Colours are tokens on .admin-ops so the inline SVG can take the same
   ones as the text beside it (the chart uses fill/stroke: var(--ops-…)), instead of hard-coding a second palette.
   Mobile first: one column, two KPI cards per row, every tap target at least 44px. Desktop goes two columns. */
