 *             binary pointers or internal flags that would break the preset if changed.
 * - 'stable-mode': Parameter is kept stable ONLY when 'Stable' randomization mode is selected.
 *                  In 'Balanced' or 'Creative' modes, these will be randomized.
 *                  Used for tuning, volume, or other sensitive but creative parameters.

 * Note: Global rules are safely ignored for synths that don't have the matching parameters.
