 Recommended use is initial setup and occasional troubleshooting. On MQTT repeater deployments, disable the panel again when finished if you want maximum MQTT heap headroom.
 
-Some constrained targets disable the panel to stay within flash limits. For example, `Xiao_C3_repeater_mqtt` builds with `WITH_WEB_PANEL=0`.

 ### Companion WiFi Additions
 
 `*_companion_radio_wifi` targets now support persisted WiFi rescue commands:

 - Pick a TFT board if this will be used as a human-facing companion or field node: `heltec_v4_tft`, `heltec_tracker_v2`, `LilyGo_TDeck`, `Heltec_T190`.
 - Pick e-paper if you want a status screen with lower idle draw and less frequent refresh: `Heltec_E213`, `Heltec_E290`, `Heltec_Wireless_Paper`, `ThinkNode_M5`.
-- Pick a headless board if this is mainly a fixed MQTT gateway and screen space is not useful: `Xiao_C3`, `RAK_3112`, `Tenstar_C3`, `Heltec_ct62`, `Generic_E22`.
