 * input-left (#3), no Calculate button (#17), container gap ownership (#22),
 * uniform 1px borders / no decorative left rail (#11/#30), field label separation 5px (#34),
 * flipped dark tokens with text-fill and solid dark surfaces (#8/#14/#16),
 * element reset limited to li/ul/ol/dd so p/dl padding survives (#3/#37),
 * native select keeps a visible chevron + custom appearance (#33), same-row control
 * height delta <=1px (#2/#11), cumulative-interest SVG renders an empty frame on load (#10/#15),
 * schedule reflows to row cards on mobile with no horizontal scroll (#36). */
