 * Styles for the ranking page (docs/ranklist/).

 * Works in both Material colour schemes. We lean on Material's own CSS custom
 * properties (--md-default-fg-color, --md-primary-fg-color, …) so the page
 * follows the active palette, and add a couple of local variables that we
 * override under [data-md-color-scheme="slate"] for dark mode.
