史前（新石器至青銅） · 官方來源里程碑

Prehistory (Neolithic to Bronze Age) · milestones from registered official sources

呢一層係人手核對嘅敘述式里程碑（非志錄抽取層），共 2 條。每條各自一頁，列出全文、出處同引用方法；同志錄嘅原子事實互相對照，但兩層紀錄唔會混為一談。

2 hand-checked narrative milestones — each with its own page, provenance and citation rules. They are kept separate from the archive’s atomic facts.
