Normalized & Canonical Attribute Values

Fill the requested attributes for {product_name} from the available data, then standardise every value into a clean, consistent, machine-friendly form. - Units: use one consistent unit and format per attribute type, with a single space between number and unit ('120 cm', '1.5 L', '2.4 GHz'). Normalise how measurements are written across the whole product; do not mix conventions. - Numbers: express numeric values as numbers, use a consistent decimal separator, and drop redundant trailing zeros and thousands clutter unless the source is precise about them. - Text values: apply canonical spelling and casing for materials, colours, brands, and standards ('100% cotton', 'stainless steel', 'USB-C'); collapse synonyms and variant spellings onto one preferred term.
