/* ── WORKFLOWS ────────────────────────────────────────────────────────────────
 * workflows.html, after landing.css (palette, fonts, nav, footer). Drawn as a
 * drawing set: a title block, then numbered sheets A1–A5, with the linear map
 * (each discipline a transit line, each workflow a stop) as the centrepiece.
 * The tutorial pages (workflows/<slug>.html, class .tu) share it; their rules
 * are prefixed tu- and sit at the end.
 *
 * Every class is prefixed wf- because landing.css already owns .card, .cards,
 * .band and .eyebrow for the front page.
