Legacy Extraction

The current legacy docs under docs/game/*, docs/api/*, and several docs/global/* pages describe the prototype behavior.

Treat them as extracted source material for the rebuild.

Rule

If the rebuild changes behavior, do not silently diverge from the extracted prototype notes.

Either:

• preserve behavior intentionally, or
• document the new behavior and the reason for the change
