/* =========================================================
   WelcomeLab styles — the post-payment moment.

   Design philosophy:
     - This page should feel like a deep breath. The user
       just authorized money. Their nervous system is on
       alert. Calm, confident, clean — not noisy.
     - The orb behind the headline is the ONE celebratory
       flourish. Soft mint glow, fades in once, settles.
       No confetti, no fireworks.
     - One pulse on entry, then quiet. Same vocabulary as
       the verdict block in Concept Lab. Continuity matters.
     - Generous spacing. The page is mostly white space,
       reading as "important moment, room to think" rather
       than "feature dump."
     - All tokens reference design-system.css — if those
       fall through, hard-coded fallbacks keep things safe.
