processDimension = (dimension) => {
	if (!dimension) return ''; // No dimension provided
	return /^\d+$/.test(dimension) ? `${dimension}px` : dimension; // Add 'px' if it's a number
}
Processes a dimension value to ensure it is in a valid CSS format.

If the input is a plain number (e.g., "10"), "px" is appended to it.
If the input is already in a valid format (e.g., "10px", "5em", "auto"), it is returned as-is.
If the input is falsy, an empty string is returned.

@param {string | number | undefined} dimension - The dimension value to process.
@returns {string} The processed dimension with "px" appended if it's a number, or the original value.
