/**
 * Shared Button Styles
 * =====================
 * Consolidated from 13+ page-specific CSS files
 * Created: February 5, 2026
 *
 * Usage: Include this file in layouts to provide consistent button styling
 * across all pages. Page-specific CSS should NOT define button styles.
 *
 * IMPORTANT: Mixing <a> and <button> elements with .btn class
 * ============================================================
 * When using both <a> and <button> elements styled as buttons in the same
 * container (e.g., flex row), they may have different heights due to browser
 * defaults. To fix this, apply explicit height and line-height in page CSS:
 *
 *   .your-container .btn {
 *       padding: 10px 20px;
 *       height: 44px;
 *       box-sizing: border-box;
 *       line-height: 1;
 *   }
 *
 *   .your-container button.btn {
 *       padding: 10px 20px;
 *   }
 *
 * See: app-data-interop-detail.css for example implementation (March 5, 2026)
