 * DEPRECATED BUTTON STYLES - DO NOT USE
 * ========================================================================
 * These button styles have been replaced by the unified button system
 * in buttons.css. This conflicted with landing.css causing inconsistencies.
 * Please use the new system for all new code:
 *   - .btn .btn--primary (instead of .btn-primary)
 *   - Use .btn--pill for pill shape or .btn--rounded for rounded rectangles
 *
 * TODO: Remove these styles after all pages have been migrated to buttons.css
