// @setting number letter-spacing
//   CSS letter-spacing. Specified as a px value when font-size is the
//   $base-font-size.
// @setting string weight
//   A key from the $font-weight map. Only specify this if you want a consistant
//   font-weight used accross the board with this typeface.

//
// Each key in the $typestyles map can either be a keyed map of settings
// using any combination of the keys below, or it can be a shorthand list
// of each property value. When using shorthand for $typestyles, the first value

// is arranged in, but best practice is to do it in the order:
// [font-size] [line-height] [weight] [case]
//
// @setting number|string font-size
//   A size from the $font-size map or px value to be converted
// @setting number $x line-height
//   Multiple of line height, ratio or px value to be converted.
// @setting string weight
//   A key from the $font-weight map.
