/* ============================================================
   Onboarding flow — /register (replaces the old single-form page).

   A multi-step wizard: account creation → welcome → optional
   one-question-per-screen profile → done. The accent + background
   interpolate from the landing navy/blue toward the dashboard
   gray/teal as the user advances; onboarding.js sets the per-step
   CSS variables (--ob-ac, --ob-ac2, --ob-fg, --ob-mut, --ob-bg-top,
   --ob-bg-bot, --ob-aurora) on #onboarding-root each render.

   Recreated from the Claude Design handoff (Onboarding Flow.dc.html
   + Screen.dc.html). No bundler — plain CSS, loaded via <link>.
