/* Landplan -- dark by design, light as an escape hatch, print as a lender pack.
 *
 * Hand-written tokens rather than a framework, per decision 8.5: the dark theme
 * becomes a block of variable overrides instead of a retrofit, and there is no
 * toolchain between editing this file and seeing the change.
 *
 * Series colours come from a pre-validated categorical palette (fixed order,
 * never cycled) and are kept separate from the UI accent and from the semantic
 * status colours -- a chart series must never be mistaken for a warning.
