The three-line clamp I added with the card-height fix cut the text of
eight of the nine profiles — every description ended in an ellipsis, so
the grid told you less about each profile the more there was to say.

Measured in a browser against the built CSS: 8 of 9 clipped at 1440px,
9 of 9 at 390px. With the clamp gone, none are clipped at 1440, 1100,
900, 768, 600 or 390px.

`grid-auto-rows: 1fr` already keeps the cards in a row level, so the
clamp bought nothing it was not paying for: the row is as tall as the
longest description (230px on desktop, 205px on a phone), and the
welcome pane scrolls when the grid outgrows it.
