Align
six things, almost straight.
drag each card straight until the whole row settles flush
The relief when a card locks true isn't about a steady hand — past a certain point the drag itself finishes the alignment for you, pulling the rest of the way on its own. It's a small honesty about how snapping into place actually works: forgiveness built in past a threshold, not a demand for pixel-perfect aim.
Concepts: order, precision.
