/**
 * File: base.css
 * Purpose: Global reset, typography, core element defaults, reusable utilities and component primitives (links, buttons,
 *          lists, status messages) for Schnor Immobilien site.
 * Guidelines:
 *   - Keep selectors low-specificity to allow easy overrides in section/component styles.
 *   - Avoid embedding layout-specific rules; confine layout grids to layout.css.
 *   - Accessibility: Focus-visible styles preserved; do not remove :focus-visible outline.
