/* Mortgage Extra Payment Simulator — content styles.
   Prefix: --mep-  /  .mep-

   Reference point: a single hero payoff-time figure (the headline
   outcome), then a 3-metric row where the two "good news" figures (time
   saved, interest saved) get a shared semantic-positive treatment and the
   third (remaining total interest) stays neutral — since it's context,
   not a win.
