/*
  credits.css — the sign-in / out-of-credits modal and the "N credits left"
  badge, shared by the AI Backtester, the AI research chat and the Tax Filing
  Assistant.

  Self-contained on purpose: these three pages have three different design
  systems (backtester/style.css, the chat's own scale, the tax page's --ffc-*
  tokens), so nothing here inherits from any of them and every class is
  ff-cred-* to stay out of their way.
