/* ============================================================
   Art & Craft Studio workflow page — page-unique visuals only.
   Linked only from art-craft-studio-workflow.html. Relies on the
   :root tokens already set by homepage-redesign.css (--accent,
   --brand-2, --radius, --border, --ink, --ink-muted, etc.) and on
   shared classes from tbos-homepage.css / homepage-redesign.css
   (.hero, .final-cta, .faq-section, .section-eyebrow, …) — this
   file only adds the winding step-path and the role-grid, adapted
   from tuitiondesk-journey.css's .tj-path / .tj-stop pattern and
   re-themed to the new brand palette.
