/* ROBERIN loan calculator (대출 이자) - The New workspace (20260714a)
 * Scope: .tn-loan-* only. Finance-family DNA shared with house-calculator.
 * Gates baked in: input-left (#3), no Calculate button (#17), container gap (#22),
 * uniform 1px borders / no decorative left rail (#11/#30), field label separation (#34),
 * flipped dark tokens with text-fill (#8/#14), element reset limited to li/ul/ol/dd so
 * p/dl padding survives (#37), schedule reflows to row cards on mobile (#36). */
