3D Model: Create A Single-piece Metal Signboard Design With The Combined Name “KarthikShyamala” Written In A Continuous Elegant Cursive Handwritten Style, Without Any Gap Between The Two Names. The Letters Should Flow Seamlessly As One Connected Artwork, As If Crafted From A Single Stroke. Add A Stylish Underline Starting Beneath The Text And Extending Smoothly To The Right, Ending With A Small Heart Shape. The Entire Design Should Appear As One Continuous, Laser-cut Piece In Matte Black Metal, With A Modern, Premium, And Minimalistic Look. Place The Design Against A Light Textured Wall Background (such As White Stone Or Marble Tiles) To Enhance Contrast And Elegance.
