A standalone dev tool that renders any acdream UI panel through the
PRODUCTION renderer (UiHost/LayoutImporter/dat-sprite path + the WB mesh
pipeline for the 3-D doll), with an ImGui click-to-inspect inspector,
sample-data fixtures, markup hot-reload + write-back, and render-config
sliders. Collapses the edit→build→login→F12→eyeball loop into edit→glance.
Full v1 scope (user pre-approved): both sources (dat LayoutDesc id +
markup file), full fixtures, editable inspector + doll-camera sliders,
live doll. Seven isolated units; the highest-risk step (extracting a
shared RenderBootstrap from GameWindow.OnLoad) is sequenced first behind
a "game still renders" gate, with a studio-local-duplicate fallback. The
drag-drop designer is deferred to phase 2.
