ROCKNIX dev build — 20260827

ROCKNIX dev build — 20260827

One release per build, every device inside it. Flash an .img.gz to a card, or
copy the matching .tar to /storage/.update on a running device and reboot to
update in place without losing settings.

The device reports its build as OS version 20260827 under system information
(20260826 for GENERIC_X64), which is how to confirm what is actually installed.

Device	Hardware	Files
H700	Anbernic RG35XX SP / RG-SP / RG40XX / RG CubeXX …	-DDR3 and -DDR4 variants
RK3566	Anbernic RG353 family	-Generic and -Specific variants
RK3326	Anbernic RG351 family	-a and -b variants
GENERIC_X64	QEMU / UTM virtual machine	.qcow2, .utm.zip, plus launcher and profile

H700 variants are not interchangeable. DDR3 and DDR4 boards need different
u-boot. To tell which you have, from a running device:

for r in /sys/class/regulator/regulator.*/; do
  [ "$(cat "$r/name" 2>/dev/null)" = "vdd-dram" ] && cat "$r/microvolts"
done
# 1200000 -> DDR3    1100000 -> DDR4

Guessing wrong costs a reflash, not the device — u-boot is written to the SD
card, never to internal storage. See issue #44.

What is new in this build

• backuptool backup works again. Upstream dropped the zip package in
  January while backuptool still built its archive with it, so backups had
  failed on every image since. Restored, and declared as a package dependency so
  it cannot silently vanish again.
• A restore no longer wipes the device password. Credentials are stripped
  from backups on purpose; the boot path then applied that empty value across
  SSH, Samba, Syncthing and the file server. It now leaves the existing password
  alone (#46).
• FINISH RESTORE SETUP is clearer — plain state icons instead of alert
  triangles, an explanation under every row, the cloud check hidden unless a
  remote is configured, and LATER now says where to find the page again. That
  page is also reachable without a cloud remote, which it previously was not
  (#47).
• Long dialogs no longer overlap their buttons on small handheld panels (#48).
• Cloud sync uses a /ROCKNIX namespace (Saves, Backups, Content), and the
  system-backup archive round-trips correctly in both directions.

Pre-release: these are development builds for testing, not general use.
