## Archived material

The pre–launch rewrite README (453 lines, full technical detail) is preserved verbatim:

[../archive/readme-pre-launch-rewrite.md](../archive/readme-pre-launch-rewrite.md)

Extracted sections in this folder were split from that archive for navigation; the archive remains the complete historical record.
