  Design system: dark, cinematic, single-accent (emerald signal green).
  Type: native Apple system font stack (-apple-system / San Francisco),
  chosen deliberately so the site inherits real Apple typography instead
  of approximating it.
  Radius scale: buttons/tags = pill, cards = 20px, inputs = 10px.
  Theme is locked dark site-wide (brand decision, not system-driven).
