I've noticed that it may help to interpret the central card #4, The Beauty, first.
Makes sense. I forgot to say that I laid the cards in an arch rather than a straight line. Seven is too many for me to "hold" visually, unless they're "shaped", lol. I planned a horse shoe, but they placed themselves the other way up so The Beauty was a peak. (They ended up in a very shallow upside-down V, in fact.)
I should say that the British "lucky" horse shoe is a U - I was forgetting that the French (and I don't know who else) hangs theirs the other way up already. I always understood you had to keep it "upright", like a U, so the luck wouldn't fall out (and here, it's bad luck to hang it the other way up), but apparently in France it's expected to fly out so has to be roofed in. And this paragraph is entirely off topic.
