Tandem 4.78

• The Tools menu wears the One UI face now, the last shared surface still
  drawn as a plain 1990s list. The library main screen, the health panel,
  the wizard, the history, the error, the question and the progress bar all
  moved to the modern GTK4 look across the redesign; the "Tools" button on
  the library still opened a zenity list of doctor, backup, ports and the
  rest - the one screen a coherent product should not have left behind. It
  is a rounded-card One UI window now, one tap per tool, grouped into
  sections (Programs, Diagnosis, Your data, Community and help) instead of
  the two-level "more"/"back" list zenity forced because only eight rows
  fit its window. Every tool the old menu offered is still there, and no
  word changed in any of the seven languages.
• Safe by construction, the same way every other modern window is: gui.py
  grew a "menu" mode that draws the cards, and acao_painel_moderno falls back
  to the zenity two-level list, then to the help text, on any machine
  without libadwaita, without a display, or with TANDEM_GUI=zenity. Both
  faces dispatch through one shared acao_painel_executa, so the modern look
  and the fallback can never drift on what a tool does. A drawing failure
  becomes exit 2, never a traceback.

Install

sudo apt install ./tandem_4.78_all.deb

Then, to install whatever is missing (Wine, winetricks, Android):

tandem preparar

Not on Debian or Ubuntu? Fedora, Arch, openSUSE and the rest
have no apt to take a .deb. Use the generic bundle instead:

tar xzf tandem_4.78_generic.tar.gz && cd tandem-4.78
sudo ./install.sh          # sudo ./uninstall.sh removes it

On Arch? A PKGBUILD is attached (with tandem.install):
makepkg -si from a directory holding both, or install tandem
with your AUR helper once it is published there.
