Kiosks
The shop-floor terminal: a wall-mounted screen, a gloved hand, glare, and an operator between two jobs. Everything is bigger, fewer and unmistakable.

On the kiosk the 44px boundary is the floor, not an invisible extension: visible controls are 44px or taller, so a glove lands on what it can see.
High-contrast states
Glare washes out a 16% tint. On the kiosk a state is carried by a status hue on the label and an icon as well as the tint, so it survives a screen at an angle in full sun.

One job per screen
Clock in, pick a task, mark it done. Each screen asks one question with one primary action, and the way back is always in the same corner.
