/*
    Public site styling guidelines
    - Use the theme tokens below for color, spacing, radius, and elevation.
    - Prefer Bootstrap layout utilities for structure and keep custom CSS focused on brand styling.
    - Reuse the panel, subject-selector, and validation-summary patterns on public pages.
