Offentlig slump i realtid.

Perioder och datum överlappar; start ingår, slut utesluts. ID-sökning använder source + window_id utan datum. Markörer behåller filter och tidsgränser. Endast sparade data exporteras; antal och SHA-256 finns i JSON-manifestet.

Lokalt lagrade A + B-poster; synkronisering kan vara fördröjd. Åldern räknar UTC-kalenderdagar från den första styrkta posten, inte oavbruten tillgänglighet.
