Description

The entry Air Hub (SSD2351 core board) stays 8.0-17.9 USD above the landed-cost cap of its 59 USD price. The owner asked for a third, smaller product that uses only an ESP32-C6-MINI-1 as the controller, an EFR32MG21 and a LAN port ("增加一个迷你版本，只用ESP32-C6-MINI-1 + EFR32MG21 + lan").

Acceptance criteria:

1. Air Hub spec, design appendix, reference-board page, guide, brief and index describe Air Hub Mini: controller, radios, Ethernet, what it does and which Linux-dependent requirements do not apply, with its BOM against a cost cap.
2. Requirements whose wording assumes a Linux SoC state how they apply to the Mini; the security consequence of a network-facing MCU that also drives the CAN bus is written as a requirement.
3. Line spec, indexes, product plan, open questions and compliance matrix follow.
4. Quality gate passes: bun run docs:lint && bun run docs:build && git diff --check.
