purpose: |
  This stylesheet defines the UI presentation for the InnoExchange authentication
  pages, starting with the login page. It provides a clean, professional, and
  secure-looking sign-in interface consistent with a private portal experience.
  The styles are intentionally scoped around the `ix-auth-*` naming pattern to
  avoid unintended interference with the rest of the existing InnoExchange UI.

  The layout centers the authentication card within the viewport, creates a
  structured input/form hierarchy, supports validation messaging, and provides
  interactive styling for the password visibility toggle and sign-in button.
  The design is intentionally neutral and extensible so it can later be aligned
  more tightly with the broader InnoExchange visual system without changing the
  Razor markup structure.
dependencies: |
  - Depends on `Views/Auth/Login.cshtml` using the `ix-auth-*`, `ix-input`,
    `ix-label`, `ix-help`, `ix-field-validation`, and related class names.
  - Should be loaded by the shared layout or explicitly by the login view.
  - Assumes standard browser rendering with no external CSS framework required.
security_notes: |
  - This file is presentation-only and contains no credential-processing logic.
  - Visual states are designed to improve clarity around validation and user intent.
future_notes: |
  - This stylesheet can later be expanded to support dark mode, multi-factor
    authentication screens, access denied pages, password reset flows, and
    deeper InnoExchange branding treatment.
