Mixed-size text centred vertically

Forbidden:
  `$10` and `/month` on one line, vertically centred, so the small text floats

Instead:
  Align text of different sizes to the **baseline**, not the vertical centre. The shared baseline connects them into one reading unit; vertical centring leaves the smaller item drifting in its own space.
