- Root cause of 'steady white': fixture on Butler port2, our data only went to port1
(port data regions are independent: port1 @0x3C, port2 @0x23C)
- show mode now mirrors pattern to both ports; SHOW_DIAG=1 gives 3s off/on blink test
- Claim now verifies AERE response and warns on failure
- Docs updated with port layout note; README updated
- Merge show/hybrid paths: use dmx_a template for DMX payload and replay-extracted SL frame skeleton for RDM.
- HOSTDEMO_MODE=show runs indefinitely when secs=0; wave period slowed for smoother breathing.
- Update README with show mode usage.
