   Onboarding step indicator
   Numbered circles + labels + connector lines. Three states per stage:
     - complete:  filled teal circle, white checkmark, ink-coloured label
     - current:   filled teal-dark circle with soft halo, white number
     - upcoming:  white circle with grey border, muted number + label
   The connector line between two stages fills with teal once the LEFT
   stage is complete (mirrors the user's mental model: "I came from there,
   I'm now here, the line is the path I walked").
