/* ============================================================================
 * Drug List Search Styles
 * Purpose: Styling for Indiana Medicaid Drug List Search page
 * Updated to use dark theme CSS variables from styles/common.css
 * ============================================================================
 */

/* ============================================================================
 * DARK THEME OVERRIDES
 * Override main.css light theme base styles to ensure consistent dark theme
 * 
 * DESIGN NOTE: !important declarations are used intentionally here to override
 * main.css base styles. This is necessary because:
 * 1. Stylesheet load order is: main.css → common.css → drug-list.css
 * 2. main.css uses light theme variables (--surface, --background) for base elements
 * 3. common.css redefines variables with dark theme but uses different names
 * 4. We cannot modify main.css or common.css (shared across site)
 * 5. Page-specific overrides are the cleanest solution without affecting other pages
 * ============================================================================
