/**
 * "Patterns Dark" - the dark counterpart to `Patterns`: every filled series
 * shares the same gray ramp overlaid with a distinct black pattern (hatch / dot /
 * star / triangle / grid) - the opposite pattern color to the light `Patterns`,
 * so the texture reads as dark cuts into the gray on the dark ground. Line series
 * are gray, told apart by stroke width and dash.
 *
 * Like `Patterns`, categories are encoded by shape rather than hue, so it stays
 * legible for all forms of color blindness.
 *
 * This is a standalone theme; it does not modify any built-in theme.
