/* KERN – freely designed demo for an invented carpenter's workshop. Workshop-wall grey, graphite, oak. The finished piece comes first.
   Motion is precise and mechanical, like a drawer on good runners: words and photos slide open sideways, dimension lines draw themselves
   with their millimetres, and the wood samples travel sideways while the page scrolls down (values --p, --in, --pin from demo.js). */
