docs(D.2b): Slice 2 implementation plan — paperdoll doll + Slots toggle
8-task plan. Tasks 1-4 isolated/TDD (partition+toggle, DollCamera,
UiViewport+Type-0xD, DollEntityBuilder) -> safe for subagents. Tasks 5-7
GL/animation/GameWindow integration -> INLINE per the CLAUDE.md
"no integrate-via-subagent without full context" rule, static-doll-first
then animate, verified at build + visual gate. Task 8 wrap-up + gate.
Concrete API refs pinned this session: WbDrawDispatcher.Draw call site
(8756), animatedIds assembly (8369), SetCycle idle (3514-3571),
WorldEntity build template (3390-3431), SceneLightingUbo/Binding,
ManagedGLFramebuffer + GLStateScope, UiButton.OnClick, inventory frame
.Visible. Flagged the second-Draw-per-frame dispatcher caveat (951-959).
