Every sensory toolkit has the same problem: it is a document, and the moment you need it is the moment you cannot read a document.
One card, one move
Each card holds a single instruction. Not a menu, not a decision tree, not “try one of the following”. Pick up the set, take the top card, do what it says.
That constraint is why the set is worth having as an object rather than a page. Twelve moves on one page is a wall of text; twelve moves on twelve cards is twelve things you can do without choosing.
Designed for the actual moment
Large type, because focus goes first. Short sentences, because parsing goes with it. Matte stock, because a glossy card under strip lighting adds to the problem it is meant to solve. Rounded corners and a corner ring, because a set that scatters across the floor is worse than no set.
The reasoning stays free
The sensory overload toolkit explains what each move does and why — read it on a good day, free, in full. These cards deliberately contain none of that. Explanation is the thing you cannot process when you need them, and stripping it out is the whole design.
