 * significant digits of float noise in every generated stylesheet, well past
 * any renderer's precision. Tailwind emits six decimals, so match that and
 * drop trailing zeros so exact ratios stay clean (`1/2` → `50%`, not
 * `50.000000%`).
 *
 * Returns undefined for a zero or non-numeric denominator rather than
 * emitting `Infinity%` / `NaN%`.
