/* The hero (docs/22, the default since 2026-10-31): one plain line, three steps, and the work moving beside it.
   Desktop: the line on the left, three columns of real slides scrolling on the right. Phone: the line, then rows sliding across.
   The first hero is kept at ?hero=a (the head script sets html[data-hero="a"]); otherwise its promise gives way and its demo
   stays as How it works. Without the head script nothing is hidden. Every slide is a real run from the wall (data.js). */
