Workflow Selection Redesign

• Improved the layout and styling of workflow cards in WorkflowSelection.module.scss, including changes to borders, shadows, animations, and hover effects. Added gradient backgrounds and adjusted dimensions for better visual hierarchy.

Icon Additions

• Added new icons (e.g., FiMessageCircle, FiCpu, FiLayers) to page.tsx for potential use in navigation or feature highlights.
