 * Dialog content variants with improved mobile responsiveness.
 *
 * Mobile behavior:
 * - Mobile phones (< 640px): Uses calc(100% - 2rem) width with better 1rem margin on each side
 * - Small tablets (≥ 640px): Uses calc(100% - 3rem) width with 1.5rem margin on each side
 * - Medium screens and up (≥ 768px): Uses fixed max-widths based on size variant
 *
 * Size variants:
 * - sm: max-w-sm (384px) for compact dialogs
 * - default: max-w-md (448px) for standard dialogs
 * - lg: max-w-lg (512px) for larger forms
 * - xl: max-w-xl (576px) for detailed content
 * - 2xl: max-w-2xl (672px) for wide layouts
 * - full: Takes available width with margins
