/*
  Auth cards: /login and /signup. Served at /assets/auth.css, loaded AFTER
  /assets/redlens-tokens-core.css (fonts, tokens, reduced-motion switch; see
  docs/design/design-system.md). Session 8 (2026-11) moved both pages' inline
  <style> blocks here and onto the tokens. Visual only: every id, class and the
  DOM shape the page scripts rely on is unchanged (login-2.js hides the email
  and password inputs through their parentElement, signup-5.js rewrites the
  first .card in place, password-strength.js inserts its meter after #password).

  Rules: tokens, not raw hex / px font sizes / ad-hoc radii
  (tests/test_funnel_design.py checks this file).
