baseline — which forces .agent's line-box to grow ~5px upward to
fit the 16px element. That growth makes .head taller, and
align-items:center re-centers .ts downward. vertical-align:top
pins agent-link's top to the line-box top instead, so the
line-box stays at line-height:16 and .ts doesn't shift. */
