/**
 * A camera stated in whichever form one can be given in: the west, south, east, north list
 * boundsToBbox hands back, an ENVELOPE string as `dcat_bbox` holds one, or anything else MapLibre
 * reads as bounds. Nothing at all for a string that says something else, or for numbers that don't
 * describe a box - a camera that can't be pointed is worth reporting rather than guessing at.
 *
 * The east edge is carried past the west the way unwrapEast does, which makes this the inverse of
 * boundsToBbox: a box that crosses the antimeridian is read back as the strait it covers rather than
 * as the rest of the world, so an area a reader asked to search can be handed straight back.
