Open index.html locally. One child question and actual looking/trying remain central; this helper only provides a large preparation proposal and short question → before → adult placement → look/tell reminders. One control/chunk at a time. Flat/creased and closer/farther mark proposals are suggestions, not real verified conditions. No physics simulator, result, stronger-form promise, required fold pattern, repeat count or full child log. The after panel deliberately stays blank; changing a control never records an actual trial.
Complete paper route: ask a child question; capture a prediction before a genuinely new action; inspect actual unloaded form; adult places one approved light card if safe; note actual observation/interruption in one shared row with useful individual response/support. Or use exact supplied model/report/director/no-contact access, physical trial NOT TRIED. No device, print, touch, personal fields or purchase required. JavaScript off hides inactive controls and retains full static proposal/paper/sign/AAC route.
Actual setup/safety/material identity/access remain adult-local decisions. Preparation, eight exact A4 alternatives. Models/reports do not become child direct sensory evidence. Short activity first, exact plan words/adult notes expandable. No held AJ/AK source/key loaded. Native keyboard/focus/reset/reload; no network/storage/score/upload or persistence.
