/* =============================================================================
   /signup/ — page-scoped stylesheet
   -----------------------------------------------------------------------------
   Ported from the reference design (intelio-signup-mockup.html). Every rule is
   namespaced with .su-* so nothing here can leak into the shared header/footer
   (which keep using /css/styles.css). Loaded AFTER /css/styles.css on purpose.

   Additions on top of the reference (the reference is a static mockup and has
   no server-error / loading / validation states):
     .su-errors / .su-error        — server error banner region
     .su-field-errors              — per-field error text
     input[aria-invalid="true"]    — invalid field state
     .su-btn[aria-busy] / spinner  — submit loading + disabled states
     .su-social-note               — "Google sign-in unavailable" notice
   ============================================================================= */

   For !important author declarations the cascade REVERSES layer order, so a

   Living in the same `base` layer means our higher-specificity selector wins
   deterministically and the headings render at the reference weights.
