Convert between decimal numbers and medieval Cistercian monastic numerals.
Medieval Cistercian monks recorded any number from 0 to 9999 in a single glyph built around one
vertical stem. The number is split into units, tens, hundreds, and thousands, and each digit places a
stroke in its own quadrant: units top-right, tens top-left, hundreds bottom-right, and thousands
bottom-left. Enter a number to draw its glyph, or type the four positional digits to read one back.
