/* =====================================================
   Public signup funnel
   =====================================================
   Served from this origin, deliberately.

   These pages used the Tailwind CDN like the rest of the portal. That is a
   third-party script with no SRI and no CSP, and on /signup/verify it would
   have been running on the one page in the product that rendered three
   plaintext passwords as text (security review, MEDIUM-6). That page is gone
   - V041 replaced it with /signup/set-password - but the reason survives the
   page: that form now RECEIVES a password, which is no better a thing to hand
   a compromised CDN than showing one. /signup is no better again: it collects
   the email, school name and KVKK consent of every prospect, and a
   compromised CDN rewrites a form as easily as it reads a password.

   The whole public funnel is therefore self-hosted. login.html and the
   authenticated portal still use the CDN - pre-existing, and a separate job.

   Palette matches pages/login.html so the public pages read as one product:
   primary #7DBF9E, secondary #A8D5BA, background #F4FAF6.
