- Remove hard-coded button sizes (48×32) from toolbar icons; buttons now use default ImGui sizing, matching the existing copy-camera button.
- Remove the Unload button (available via menu).
- Add ImGui_ColorButtonEx widget with per-corner rounding via ImDrawFlags, enabling segmented button-group visuals.
- Use segmented rounding for the pause/viscous/play triplet: rounded-left, square, rounded-right.
- Make pause and play buttons 40% wider than the viscous button for emphasis.
- Replace the theme combo dropdown with a cycling button.
- Reduce toolbar height from 48px to 34px and vertically center content via WindowPadding.
- Zero out table CellPadding in the toolbar for precise vertical centering.
- Remove the speed combo's inflated vertical padding.

* **Dynamic Full-Window Scaling**: Charts in the Performance and Solver panels now expand to fill the entire pane, automatically arranging side-by-side or stacked based on window orientation to eliminate scrollbars.
* **Responsive Decorators**: Added reusable C++ ImPlot helper functions that auto-hide titles, legends, and tick labels when the plot surface is small.
* **Cleaner Visualization**: Refined chart titles (e.g., "CPU msec vs frame", "Convergence vs iter") and removed redundant axis labels for improved scannability.
These changes were based on the plot behavior of //third_party/mujoco/src/experimental/py/sample/implot.py This is an incremental improvement, we can make the plots even nicer in future.

- Reorder Physics section, move Actuator Groups to end.
- Rename "Physics Settings" → "Physics", "Rendering Settings" → "Rendering".
- Reduce IndentSpacing from 20 to 6.
- Reduce FramePadding Y from 6 to 2 for narrower buttons and popups.
- Remove explicit Unindent/Indent overrides in Rendering and Visibility Groups
sections so buttons are naturally indented under their tree nodes.
- Dynamically adjust convergence and counts plot X-axis limits based on actual
solver iterations instead of hardcoded 20.

Texture IDs were assigned using textures_.size() + 1, which is not monotonic: after erasures the map shrinks and previously used IDs can be reassigned to new textures. This causes multiple ImGui images to reference the same underlying Filament texture, rendering them all with the same pixel data. This fix replaces the size-based scheme with a monotonically increasing counter (next_tex_id_) that never reuses IDs.

This change modifies the Warp JAX FFI to register callbacks for both CUDA and CPU platforms, allowing Warp kernels to be launched on CPU devices. MJX's io.py is updated to allow Warp to use CPU devices if no CUDA GPU is available. Tests are adjusted to no longer skip when CUDA GPUs are absent. A minor fix for sorting precision in test_util.py is also included.

* Remove the explicit io.Fonts->Build() call from InitImGui, which was deprecated in Dear ImGui v1.92.0. With ImGuiBackendFlags_RendererHasTextures already set, the font atlas is now built lazily by ImGui and communicated to backends via the ImTextureStatus_WantCreate protocol.
* Add proper texture shutdown in ~ImguiBridge by iterating ImGui::GetPlatformIO().Textures and destroying all tracked textures, per the //third_party/dear_imgui/docs/BACKENDS.md instructions.
* Remove the "OK but missing" and "WantUpdates but missing" texture recovery hacks from Update(). These handled a state where ImGui thought textures were alive but the Filament-side storage had been torn down. With proper destruction acknowledgement (SetStatus(Destroyed) + SetTexID(Invalid)), ImGui will now transition destroyed textures to WantCreate on the next frame, and the normal creation path handles it cleanly.

This is a combination of minor tweaks to the existing Studio WASM application, CMake cleanup to make it buildable, and integration with GitHub Actions for deployment.
The new features added are drag-and-drop, model specification through `?model=` URL parameter, HTTP and HTTPS resource provider, and a user-visible loading message while the model is loading.

The filament library provides APIs for creating the low-level
objects such as meshes and textures. The compat library provides
the high-level compatibility layer between mjvScene and the core
library.

Refactor FilamentContext to allow multiple render requests to
be submitted onto a single RenderTarget. The main scene and the
ux scene are then submitted as two separate requests that share
the same target, resulting in a single, composited render.

Do not allow a mix of `elastic2d != none` with `dof = trilinear` since the latter assumes 3d elasticity.
Also, do not assume that `flex_interp > 0` in the engine. This will enable to use, e.g., `flex_interp = -1` to mean a linear surface finite element instead of a 3d finite element which is currently identified with `flex_interp = 1`.

The reference node positions and the positions used for computing stiffness eigenvectors were previously stored in world frame. However, the runtime expects these quantities in the unrotated local frame. This caused non-zero constraint residuals and simulation instability when the grid was rotated — either by the parent body's initial orientation, or by the flexcomp's own frame attributes.
Rather than tracking each rotation source individually, this change extracts the total grid rotation directly from the cell geometry. All node positions are then un-rotated before computing the stiffness matrix.
