/* OPRA Subscriber Agreement step (opra_agreement.html), rebuilt 2026-09-23 as a
   three-pane wizard inside the auth/onboarding shell (auth_base.html, wide card).
   Loads after style.css and content.css, scoped to the opra- prefix so it never
   leaks. Shared components used as-is and NOT restyled here: .btn/.btn-primary/
   .btn-ghost/.btn-sm, .auth-submit (+ its .is-loading spinner), .auth-field,
   .auth-status-msg, .auth-status-icon, .auth-status-actions, .onboard-steps,
   .callout-note, .eyebrow, .auth-brand-*. Where this file touches a shared
   class it does so only through an opra- prefixed parent selector, per the
   design-system hard rules. */
