 Since 1.17.1.4, this branch also includes USB session and contact-persistence
 fixes, automatic nRF52 ExtraFS recovery, improved Indicator setup/display
 handling, compressed MOTA transport, and measured ESP32 memory limits.
+Qualified internal-flash nRF52840 receivers now reserve 64 KiB of retained

+Install that bootloader before relying on LoRa updates from these new hybrid
+receiver images: they reject application containers larger than one flash
+page when the installed bootloader lacks the retained-RAM capability.
+QSPI/microSD roles and Full Companions retain their existing storage layouts.
+An interrupted hybrid download must be fetched again after an application
+restart or power cycle. See the [protocol](../ota_protocol.md) for the exact
