 * LM CRM — Tailwind CSS — Custom base styles
 * 
 * This file contains only styles that Tailwind utility classes can't handle:
 * - CSS custom properties for theming
 * - Sidebar layout (fixed positioning, transitions)
 * - Dark mode overrides
 * - Component styles that are too complex for utility classes alone
 * - Print / responsive overrides
