Description

The owner dropped the SigmaStar path for Air Hub and locked the Linux products on RK3506 stamp-hole core boards ("我们当前的air hub的规格抛弃ssd202d方案，锁定3506g和3506j方案，分别是128+256 或者256+256，另外一个是esp32-c6 作为主控的方案"):

• Air Hub: RK3506G core board, 128 MB RAM + 256 MB NAND (replaces the SSD2351 core board).
• Air Hub Pro: RK3506J core board, 256 MB RAM + 256 MB NAND (unchanged).
• Air Hub Mini: ESP32-C6 as the only controller (unchanged).

Acceptance criteria:

1. Air Hub spec, design appendix, reference-board page, guide, brief, index and platform evaluation describe AH-19 on the RK3506G core board with its memory, CAN source, temperature range and BOM against the 59 USD cap; SSD202D and SSD2351 remain only as evaluation records.
2. Switch line spec and index, product plan, open questions and compliance matrix agree.
3. Quality gate passes: bun run docs:lint && bun run docs:build && git diff --check.
