/* Chart tokens (docs/DASHBOARDS.md "Colour", common::charts::SeriesColor).
   Categorical slots are the dataviz reference palette, validated against
   our surfaces (#192d3d dark, #ffffff light): all checks pass in dark;
   in light, slots 3/4/5 are under 3:1, so charts using them must show
   direct labels or the table view (every chart has one). Severity charts
   use the design-system colours, except dark critical: #e5194a sits too
   close to sev-high (#ff5b45, deltaE 11 < 15), so charts use #c0145a
   (deltaE 18.4). Severity is always labelled (word or letter). Status
   tones are fixed in both themes and always come with an icon. */
