/**
 * "Petroleum" — a restrained, near-monochrome dark theme: gas-flare gold text on
 * a near-black crude ground, with a tight gold palette and a single industrial-
 * green accent.
 *
 * Palette: deep crude `#141a1a`, oil-slick `#1e2824`, pipeline green `#3a5040`,
 * crude amber `#c8890a`, sulfur `#a89050`, gas-flare `#f5d090`.
 *
 * This is a standalone theme; it does not modify any built-in theme.

 * @see {@link https://www.amcharts.com/docs/v5/concepts/themes/} for more info
