/*
 * Smart Contact Form — Frontend Stylesheet v1.1.0
 * Author:  SunoTimes (https://sunotimes.com)
 *
 * Design goals:
 *  - All rules scoped under .scf-* to avoid theme collisions
 *  - box-sizing: border-box applied locally (not globally)
 *  - No resets that can break theme typography
 *  - CSS custom properties for full theming via Settings → Style
 *  - High-contrast focus rings that satisfy WCAG 2.1 AA
 *  - Fully responsive; 2-col → 1-col below 600 px
 *  - Dark-mode aware via prefers-color-scheme
 */
