/**
 * Linearly maps a value from one range into another.
 *
 * @param value     The input number.
 * @param fromLow   Lower bound of the input range.
 * @param fromHigh  Upper bound of the input range.
 * @param toLow     Lower bound of the target range.
 * @param toHigh    Upper bound of the target range.
 * @param clamp     If true, clamp the result to [toLow, toHigh] (default true).
 *
 * @returns The mapped (and optionally clamped) value.
 *
 * @example
 *   // UI slider 0-100 → spring ζ 0-1
 *   const zeta = mapRange(37, 0, 100, 0, 1);          // ≈ 0.37
 *
 *   // reverse:  damping ratio back to slider
 *   const slider = mapRange(zeta, 0, 1, 0, 100);       // 37
 *
 *   // overshoot mass 1-5  → slider 0-100, clamped
 *   const slider2 = mapRange(6, 1, 5, 0, 100, true);   // 100
