/* Tricker — market board
   Near-black ground, heavy display type, and one loud move: every ticker is set
   in bright white. Colour belongs to the assets themselves — each carries its
   own brand hue in its icon, and nothing else competes with it.
   Dark is the design; the light palette below is what the theme toggle swaps to. */
