Continues the build order past Options/Scheduler/Speed Limiter/Batch/ Grabber/tray. - DropTargetWidget: frameless always-on-top drop target (docs/03-gui-spec.md §5), position persisted, accepts a dropped http(s) URL or link text and opens FileInfoDialog directly (skipping Add URL, since the URL is already known). Shown/hidden from general.showDropTarget, live via event.settings.changed, same pattern MainWindow already used for general.minimizeToTray. - Clipboard, explicit path #2 (docs/06-risks-and-spikes.md R2): GlobalShortcut wraps org.freedesktop.portal.GlobalShortcuts (CreateSession -> BindShortcuts -> Activated), triggering the same Add URL flow. Guarded end-to-end on `if(TARGET Qt6::DBus)` / VELOX_GUI_HAVE_DBUS so a build without the component degrades to "feature skipped," not broken (gui/docs/pkg-qa-requests-m1.md R4). Best-effort by design per the risk doc: fails silent, never advertised. Verified live against the real portal (a real Wayland session, not just offscreen): `CreateSession` refuses every caller with "An app id is required" — reproduced identically via a bare `busctl` call with no Qt involved at all, so this is the portal requiring a sandboxed caller identity, not something fixable from an unconfined process. Recorded as a partial Spike S2 answer in docs/06-risks-and-spikes.md: this explicit path likely doesn't work for Velox as a traditionally-packaged app on stock GNOME, only if/when it ships confined. Also fixed a real leak this verification caught: QDBusInterface's introspection cache reads as a LeakSanitizer leak the first time anything touches D-Bus (tst_rtl went red under ASan) — switched to QDBusMessage::createMethodCall, which needs no introspection. - Theming (docs/03-gui-spec.md §7): gui/resources/qss/{idm-like,dark}.qss, each with a documented palette block up top (QSS itself has no variable syntax), applied by ThemeManager and kept live via QStyleHints::colorSchemeChanged. util/Theme.hpp gives the handful of inline C++ styles (status dot, offline banner, the eleven identical error-label styles across dialogs) named constants instead of a twelfth copy of the same hex. - UiThreadWatchdog: the M1 DoD's 200 ms debug-build watchdog. A background std::thread pings the UI thread every 50 ms via a queued invokeMethod and warns once (not per-poll) if a ping goes unanswered past 200 ms; no QThread, no Qt event loop of its own, so the watchdog itself can never be what blocks the thread it watches. No-op in a release build. Proven both ways in tst_uithreadwatchdog: fires on a genuinely blocked UI thread (synchronous sleep, no processEvents) and stays silent on a responsive one. Full non-conformance suite (55 tests across every lane, `ctest -LE conformance`) passes clean at this point, including the whole gui label under ASan+UBSan.
