Remove the deprecated border.scss stylesheet and its import from the main SCSS entry file. Replace all legacy border utility class usages with explicit border classes: - Replace border-ff with border border-white - Replace border-F1F5F9 with border border-[#f1f5f9] - Replace border-bottom with border-b border-[#e5e8ee] - Replace border-top-8 with border-t-8 border-[#f5f5f5] - Update border-none button styles to add after:!hidden to retain original pseudo-element hiding behavior
