I would love to see a working demo (preferably linked from the README in the repo)

Demo doesn't work: 404: NOT_FOUND Code: DEPLOYMENT_NOT_FOUND ID: cle1::tpv5g-1751207033791-4081486be439

Note persistent typo in README on "orchesration". Not enough time to add anything more constructive today, but I've used stepper forms and they're harder to get right than you naively imagine.

FE ecosystem is broken with validation as first-class citizen. Remember that parse, don't validate.

Stop making validation as first-class citizen, use a generic async function instead.
