/*
 * Step-by-Step Guide — the shared kit for every page under /step_guides/.
 *
 * Built by prompts/p_step_by_step_update.md (Appendix A). One stylesheet for guide 0 (the table of
 * contents) and the seven walkthroughs, so they read as one product. Tokens are copied from
 * site/css/v4-template.css (the homepage template), not imported: these pages are static HTML
 * outside Docusaurus.
 *
 * Layout of a walkthrough page (A.2):
 *   .g-top                      the site's top bar (logo, Step-by-Step Guide, Get Started)
 *   .g-wrap > .g-rail           left step rail, 20% of the width or less, sticky on desktop
 *           > .g-main           the wide right area: title, goal, Continue, screenshot, Continue, detail
 *   .g-foot                     the site footer
