+<!-- Custom copy glyph. lucide's `Copy` draws the back square as a bracket that
+     stops ~4px short of the front square, leaving a visible gap that reads as two
+     disconnected shapes. This redraws the same two-square copy mark in lucide's
+     exact stroke language (24px box, 2px round stroke, currentColor) but runs the
+     bracket's two open ends onto the front square's left and top edges, so the
+     back square reads as continuously joined to the front one. Single <svg> root,
+     so it inherits the button's [&_svg] sizing and any passed size-* class. -->
