- PlayerCard removed — it duplicated the sidebar editors; the character
page now shows only prepared spells and attunements
- headings are plain RU: Заготовленные заклинания / Атюнменты
(no EN/RU double labels; h6 no longer lowercased)
- Attunements is Vec<Option<String>> instead of a fixed 3-slot array;
'+ слот' appends a slot, so custom campaigns can track more items
(old saved JSON parses: arrays map to Vec)
- PlayerData.ac (u8, serde default 0): manual armor-class input in the
sidebar HP block (hp/оз, ac/КД), editable like the HP numbers
