Replaces the radio+continue layout with a Steam Cloud Conflict
lookalike: uppercase title with circled-! glyph, three-line body
copy, two large card-buttons (Cloud Save / Local Save) each showing
icon + label + 'Modified <date>', Cancel bottom-right. Card click
commits the choice and dismisses — no separate Continue button.
Background switched to Steam-blue (#1b2838) instead of Prism dark
so the dialog reads as a 'pay attention' moment rather than another
status pane.
Card glyphs are unicode placeholders (☁ / ▢) — easy SVG swap later
if we want crisp HDD/cloud icons.
API change:
prompt_conflict_qt(local_summary, remote_summary)
→ prompt_conflict_qt(local_modified, remote_modified, save_label)
Caller now passes pre-formatted timestamp strings + an optional
noun phrase ('Minecraft save').
Login dialog (prompt_login_qt):
Modal asking for a discord_id:password token. Echo masked. Validates
format before accepting. 'Skip cloud sync' returns None so caller can
bypass sync without blocking the launch.
Conflict dialog (prompt_conflict_qt):
Modal with three radio options — keep_local, use_remote, cancel.
Shown when local files were modified since the last pulled snapshot
AND the remote has a newer snapshot from another host (divergence
state.json detection happens in sync.pull; not wired yet).
Both reuse the Prism dark palette via _apply_prism_dark. Tk fallbacks
not implemented — Qt is the path most players will hit.
Next: state.json (last_pulled_snapshot_id), divergence detection in
sync.pull, integration with these dialogs.
cloud-sync now ships a real Qt UI alongside the tkinter fallback.
Architecture:
- HeadlessProgress: --no-gui path, plain stdout
- TkProgressWindow: stdlib fallback when Qt isn't installed
- QtProgressWindow: preferred path; supports both PySide6 and PyQt6
(interchangeable APIs for our subset)
The factory in ui.py picks Qt → tkinter → headless. Tk stays so the
zipapp still works on bare Python with no extras.
Threading: QApplication runs on the main thread (started by run_with
via QDialog.exec). The restic worker runs on a daemon threading.Thread.
Cross-thread UI updates go via a Signal on a bridge QObject so Qt
auto-marshals them onto the main thread via a queued connection.
Cancellation: WM close + Cancel button both set a flag. sync.pull/push
pass ui.is_cancelled as restic.run's cancel_check; the subprocess gets
killed and returns -1 → exit 1.
Theme: Fusion style + Prism's dark palette (RGB values copied as facts
from PrismLauncher's DarkTheme.cpp). Override with PRISM_THEME=off.
Pyz size went 20 KB → 36 KB (added ui.py + ui_qt.py).
33 tests still green.
