## Specification

Daily cash movement as a heatmap. Sequential OKLCH lightness ramp within one hue for magnitude, with the diverging in/out distinction carried by **two separate ramps that differ in lightness**, not by red/green.

## Rules this component obeys

Money is minor units, never floats. `null` is not `0` and neither is redacted. Negatives render in accounting parentheses with the parenthesis column reserved on both sides. Debit and credit are two columns. Per-currency decimal places. Polarity is explicit — up is not always good. Every figure states its period, entity, currency, basis and as-of.
