The paper uses a position-based grid with a dedicated tear band. It resists folding more than cloth, then gives at the perforation once enough strain builds up.
Mouse + Trackpad
Left-drag the receipt to grab. Drag empty space to orbit. Scroll to zoom. Press R to reset, Space to pause, and H to hide this panel.
Touch
One finger on the paper grabs it. One finger on open space orbits. Two fingers pinch to zoom while moving the camera around the strip.
Tear Mechanic
The dashed perforation band has weaker cross-constraints. Pull across that band until the status changes from attached to tearing, then detached.
Reduced Motion
Reduced mode lowers particle density and removes non-essential idle sway while keeping core interaction, drag, tear, and fall intact.
