 * System serif stacks only: Charter on Apple devices, Sitka/Cambria on
 * Windows, a generic serif elsewhere. A web font would be one more request to
 * one more company for a site that exists partly to keep a low profile, and
 * reading text set in the reader's own system serif is a fine thing anyway.
 *
 * "More" is Russian for sea, which is where the accent comes from.
