/* ============================================================
   Singapore Tuition Centre Workflow — page-unique visuals only.
   Loaded after styles.css, tbos-homepage.css, homepage-redesign.css
   on singapore-tuition-centre-workflow.html ONLY. Everything else
   on the page (hero, buttons, FAQ accordion, final CTA) reuses the
   shared .hero / .hero-visual / .faq-* / .final-cta components that
   homepage-redesign.css already styles under body.tbos-home — this
   file only adds the hero "cohort orbit" diagram and the step-path
   timeline, adapted from tuitiondesk-journey.css's ecosystem/step
   pattern and re-themed with the redesign's palette and fonts.
