say plainly what the rest of the wiki is for
The home page described the other pages as covering everything after first boot,
which reads as though they are the next thing to work through. They are not:
they are gotchas and technical detail for when something is not straightforward.
Saying so sends people to the setup guide and leaves the wiki as the place to
come back to.
Point the home page at the setup guide instead of listing images
The board table hardcoded twenty seven download urls at a fixed version, so it
was serving 26.06.01 while 26.07.01 had been current for weeks, and nothing here
updates it -- it drifts on every release and has done so quietly for years.
The setup guide on syncloud.org reads the release list from github, so it cannot
go stale, and it walks through writing the image and activating the device
rather than handing over a file and wishing you luck. Every board that was in
the table is still offered there.
What is left here is what a wiki home page is for: what the project is, where to
start, what the other pages cover, and where to ask.
Home: bump image download links to 26.06.01
Bump image links 26.04.7 -> 26.04.9; add legacy HC4 image entry
Older non-LCD HC4 boards now have a dedicated legacy image (older kernel,
same rootfs) shipped in current releases, replacing the 25.12.1 fallback.
HC4 page no longer hardcodes distro/kernel versions or a specific image
version, so future migrations only require updating Home.md.
Home: bump image links 26.03.2 -> 26.04.7
Update download links to 26.03.2 release
