Data is the value to encode; only ASCII 0–127 is accepted (an out-of-range character raises an exception).
Symbology selects the barcode standard; Code 128 (bsCode128) ships today, auto-switching between subsets A/B/C for the most compact encoding.
ModuleWidth sets the pixel width of the narrowest bar; Height sets the bar height.
ShowText prints the encoded Data under the bars.
Color paints the bars and text; BackgroundColor fills behind them.
GetSVG (also used by HTML) returns the inline SVG markup, wrapped in a sgc-barcode container.
