ui-preview: hold <id or key> <pseudo> - hover, active, focus, focus-visible, checked or disabled held on from the next frame on top of the real input, by the element's key (so through model and load), let go with "" or reset; ludic.ui's held.ludic keeps them and the matcher asks it first; protocol-v1.md and smoke.txt

# on top of the real input (ludic.ui's held.ludic); "" as the pseudo lets that element's holds go, and
# "" "" every hold. Holds are by the element's key, so they survive `model` and `load`; `reset` clears.
