Web demo playusable

gear-grinder renders as a engineering toy model with adjustable controls, a checklist, and public safety copy.

Keep rendered route, console, network, and safe-copy checks attached before release embedding.

Native mobile screencontract ready

The surface uses touch-sized controls, a single-column mobile layout, no hover-only actions, and no raw child media capture.

Port the same controls into the native shell and verify phone, tablet, offline resume, reduced motion, and bottom-rail navigation.

ChromeOS input paritycontract ready

The web surface keeps range controls, stepper buttons, evidence capture, and review links available to keyboard, pointer, and touch users.

Capture Chromebook-class keyboard, pointer, touch, reduced-motion, and timing proof before widening classroom rollout.

Keep the activity local-first, age-appropriate, and behind teacher review before public sharing.
No real turbine construction, electrical generation, grid, weather, or infrastructure claims.
No raw device data, child media, or biometric input.
