- Lock screen: full ambient scene above the unlock form (the idle 'screensaver'
— wallet auto-locks here) instead of a thin banner.
- History ('home'): full scene as a top banner.
- Send/Receive: IdleDoge — a small click-through sitting doge in the corner,
the 'most quiet' idle for task screens.
- Mining keeps its own scene.
All gated by Config::reducedMotion (scenes freeze, doge shows a still frame).
Reusable SceneWidget (QQuickWidget host) loads scene.qml — dusk sky, tiled
grass, running doge, bouncing WOW coins (slowed per feedback), drifting
money — and feeds it Config::reducedMotion so it freezes to a still when
that's set. First placement: a banner atop the unlock form. Scene rendered
& verified at banner + screensaver aspects via local qml6 harness. Assets
from wow-lite-wallet (friend's). Home banner / idle screensaver / per-tab
idle to follow on the same SceneWidget.
