/*
  Talent direction contract
  THESIS: Talent is the human infrastructure behind CUHK’s next chapter; the page
  refuses a long, undifferentiated card list by keeping the people story visible.
  OWN-WORLD: white editorial hero, F2F2F7 strategy canvas, open strategy rows,
  purple/cyan accents, and one dragon-boat closing image.
  STORY: visitors meet the talent direction, scan its seven commitments in an
  open two-column list, then land on the closing image before the footer.
  FIRST VIEWPORT: the title and student composition establish the direction before
  the strategy list begins.
  FORM: desktop two-part hero; tablet and mobile return to normal document flow.
