 *   stem centre       0.1525em from the letter box's left edge
 *                     (NOT 50% — letter-spacing folds into the box)
 *   tittle underside  aligned by UNDERSIDE, not centre: the ring is
 *                     bigger than the dot it replaces, so matching
 *                     centres drops it onto the stem.
