- Replace the broken App::new() (which does not exist) with AppBuilder.
- Strip it down to the PLAN's ~15-line target: no explicit winit/wgpu,
AppHandler render() left empty (scene rendering still on the roadmap).
- Verified: builds, opens a black window and runs the update->render->present
loop until closed.
- Update README/PLAN wording now that the simple example compiles (it still
does not draw a scene).
- README stays the source of truth for current state; drive/item-5 now
reflects the settled decision: String IDs for the MVP, slotmap deferred.
- ROADMAP gains a 'point de depart' (present-state) block, marks glam done,
removes the slotmap Phase-1 mandates, and documents the String-ID decision
plus the deferred 'typed handles' step.
- PLAN corrects stale [X] checkmarks (App render() cannot draw, Scene
rendering not automated, simple example does not compile) and notes its
verification checklist against current reality.
- Remove the unused slotmap direct dependency from wsg-lib (package remains
in Cargo.lock only as a transitive dep of glow).
