 """Shared app-wide constants: paths, palette, theme.

+Paths follow each system's own per-user conventions (no admin needed):

+    ~/.config                 %APPDATA%       (settings; roams with the user)

+    ~/.cache                  %LOCALAPPDATA%  (caches, in a Cache/Downloads subfolder)
+so the SaraSuite layout below them (SaraSuite/<Program>/...) is the same on both.
+
 The palette and theming mirror SaraFem's Core.py (which mirrors SaraView's),
 and read the same shared ~/.config/SaraSuite/Themes/*.toml files, so a theme
 picked for one Sara program looks the same in all of them.

+
+| Linux | Windows |
+| --- | --- |
+| `~/.config/SaraSuite/` (settings) | `%APPDATA%\SaraSuite\` |
+| `~/.local/share/SaraSuite/` (programs, receipts) | `%LOCALAPPDATA%\SaraSuite\` |

+| desktop entry | Start Menu shortcut (`[[Shortcuts]]`) |
+| systemd user service | `ServiceRun.py`, started at login by a shortcut in the Startup folder; its PID is in `%LOCALAPPDATA%\SaraSuite\Services\<Name>.pid` |
+
+Linux without systemd (no `/run/systemd/system`: runit on Void, OpenRC, s6, dinit, ...) runs
+services like Windows does (`Services.py`): `ServiceRun.py` runs them, started at login by an XDG
+autostart entry, `~/.config/autostart/<Name>.desktop`, which desktop sessions start whatever the
+init system is. It restarts a service 10 seconds after it fails, like the unit's
+`Restart=on-failure`, and keeps its output in `~/.local/share/SaraSuite/Services/<Name>.log` (its
+PID next to it, in `<Name>.pid`). Units aren't written there, and `RestartUnits` stops the process
+instead (D-Bus starts `xdg-desktop-portal` again when it's needed). A window manager that doesn't
+run XDG autostart entries needs to start them itself (e.g. `dex -a` in its startup config).
+| system `python3` | the `py` launcher / `python.exe`; if there's none, SaraSuite installs Python for the user with winget |
+| AppImage self-update (rename over it) | `.exe` self-update (the running one is renamed to `SaraSuite.old.exe`, deleted on the next start) |
+
+Programs run on Windows with `pythonw.exe -X utf8` (no console window; UTF-8 mode, since Python
+on Windows otherwise reads text files in the old ANSI code page). Nothing needs admin rights.
+Linux-only features (SaraFem's file picker portal and default-file-manager option) simply

 ## Running and building

 - AppImage: `Packaging/BuildAppImage.sh` builds `dist/SaraSuite-x86_64.AppImage`

  the header has an "Add to app menu" button.
+- Windows: `Packaging/BuildExe.sh` builds `dist/SaraSuite.exe` with the Windows Python inside a
+  Wine prefix (`build/WinBuild/`, set up on its first run), since PyInstaller can't build for
+  Windows from Linux directly. The .exe's header has an "Add to Start menu" button.
 - From source: `python3 -m venv .venv && .venv/bin/pip install -r requirements.txt`, then
