/* Equity pretrade dashboard.
   Design tokens follow the validated reference palette (dataviz skill): categorical
   slots 1 blue / 2 aqua / 3 yellow / 4 green / 5 violet / 8 orange, each with its
   dark-surface step. Series color follows the ENTITY everywhere (tiles, charts,
   model strip, legend): Es=blue, beta=aqua, sigma=yellow, volume=green,
   client-rtt=violet, server-compute=orange. Text never wears a series color —
   identity comes from the small colored key/underline beside it. */
