"""Most: policzony horoskop → tokeny sygnifikatorów → wyszukiwanie w bazie.

Zalążek LOG-15/16: z pozycji obiektów (wraz z domami) generujemy tokeny w składni
bazy i wyszukujemy pasujące rekordy. Dla każdego obiektu tworzymy kilka **faset**:
- „w znaku"  — planeta + token znaku (`[Su` + `[Tau`)
- „w domu"   — planeta + token domu (`[Su` + `11th H.`)
Aspekty (`[conj`,`[sq`,`[opp`) wymagają policzenia aspektów (LOG-06) — na później.

Format skrótów odczytany z realnej bazy: planety `[Su`,`[Mo`,…; znaki
`[Ari`,`[Tau`,…; domy `12th H.`; np. `[Sa [conj [Su in 6th H.`.
