Grouped Pedersen lower bound (percentage points). Seven exact standalone INE party labels. Joint coalition combinations, independents and other parties remain Other, without allocating coalition votes. This coarse grouped comparison can conceal coalition-member shifts and requires the stated geographic/event review. An interval is withheld if either election has no list mapped to an explicit named group. This is aggregate share change, not individual voter switching.
