Enable text selection on SVG text elements by changing CSS user-select properties from 'none' to 'text' and cursor from 'default' to 'text'. Add JavaScript event handling to intercept mousedown events on text elements, preventing dragscroll interference while allowing normal text selection. This preserves the existing drag-to-pan functionality for non-text areas while making text elements selectable and copyable.
