docs(plan): Phase 1 Schwarzschild implementation plan
...
20 tasks covering: deps, minimal window, web/Trunk/WebGPU, full-screen
Material2d pipeline, orbit camera, params resource, uniforms+mirror, ray
gen, RK4 Schwarzschild integrator, CPU physics tests, lensed starfield,
Doppler accretion disk w/ Einstein halo, egui panel, storage-buffer
planets, Flamm grid, cubemap skybox, render scale, web verification,
README. Verified against Bevy 0.19 API (group-2 material bind group,
component spawning, WgpuSettings defaults).

docs(spec): correct Bevy 0.19 API details (verified)
...
- Material2d bind group is group 2 (#{MATERIAL_BIND_GROUP}), not group 1
- RenderPlugin has no wgpu_backends field; enable bevy 'webgpu' feature instead
- WgpuSettings::default() auto-selects BROWSER_WEBGPU on wasm32
- Imports from bevy::sprite_render (Material2d, AlphaMode2d)
- Component-based spawning (Camera2d, Mesh2d/MeshMaterial2d), no bundles
- getrandom 0.4/wasm_js handled transitively by Bevy

docs(spec): add desktop + web (WebGPU) platform support
...
- WebGPU-only web target (Bevy forces WebGPU/WebGL2 at build time; WebGL2
lacks storage buffers our planets feature needs)
- Add §13 Platform support: build toolchain (trunk/wasm32), backend gating,
fallback message, web defaults (render_scale 0.75, steps 200)
- Add src/web.rs, web/index.html, Trunk.toml to file structure
- Add web-sys dep; add web build + perf verification milestones
- Update storage-buffer risk note: valid on native + WebGPU

docs: add Interstellar black hole renderer design spec
...
Analyzes reference video (BH + tilted Doppler disk + lensed halo + stars),
specifies full 8-feature scope (adds cubemap skybox, lensed planets, Flamm
grid), Schwarzschild Phase 1 with Kerr Phase 2 follow-up, Bevy 0.19
full-screen Material2d architecture.
