Lattice Boltzmann flow on the CPU: model, solver, engine (M12) (#36)
Model: Newtonian fluid materials; fluid domains (box, spacing, conditions on the box faces, obstacle bodies with conditions on their named faces, initial velocity, body acceleration); fluid steps with caps. Deck writers refuse fluid steps; a fluid-only model needs no mesh in model.check; one step selector (Model::select_step) for every solver. New L2 crate modelcraft-lbm: D3Q19 two-relaxation-time collision with Guo forcing; halfway bounce-back walls (moving walls after Ladd), slip faces, periodic pairs; Zou–He velocity and pressure faces with the D3Q19 transverse correction; obstacles voxelised from the face-tagged boundary surface with exact predicates and symbolic perturbation; momentum-exchange forces per box face and per B-rep face; unit conversion, automatic time step and Mach/tau limits; bounded runs with frames and force histories. Engine: model.fluid_domain.create/edit/delete, model.fluid_domain.boundary, solve.fluid (obstacles from the open design or imported surfaces, lowerable caps), solve.probe for fluid fields and wall force histories. Fluid Domain, Inlet & Outlet and Lattice Boltzmann toolbar entries are ready. Verification (analytic): plane Poiseuille exact with Λ = 3/16 and second order (2.000) with Λ = 1/4; Couette exact with the wall shear; Taylor–Green decay second order (2.01, 2.00); staircase pipe; Stokes drag of a sphere array within 1.7% of Hasimoto at R = 6; Zou–He channel; mass conserved to round-off; bit-for-bit reproducibility. Benchmark: Schäfer–Turek 2D-1.

Results display (M4) and offscreen full-UI capture (#28)
* ui.capture: the whole window drawn offscreen and rasterised on the CPU ui.screenshot falls back to it when no frame is presented (hidden window, locked screen), so agents can look at panels and the toolbar. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Draw the open design and imported surfaces in the viewport DisplayMesh keeps node labels on every element primitive (for results), gains add_surface (geometry faces and their boundaries, coincident points welded) and displaced (elements moved by nodal offsets). Bodies are tessellated at a thousandth of their size; meshed models show the geometry as boundaries only. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * results.* commands: deformed shape, contours, mode shapes, animation, reaction sums The results display is session state (ResultsView), set by commands that are not edits. Nodal fields (displacement, von Mises, principal and component stresses; principal stresses in closed form after Smith 1961) and reaction force and moment sums per set. Results kept from an earlier revision stay viewable, marked stale; solve.probe says when a result is stale. The Results tab's display and reaction entries are ready. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Results display: deformed shape, contours with legend, mode shapes and animation, probe, reaction sums The viewport draws the session's results view: elements moved by their nodes' displacements or a mode shape (automatic or given scale), faces split exactly along contour band boundaries into flat-coloured pieces (same on GPU and CPU), a legend with levels and extremes, a results panel whose controls run the results.* commands, a click probing the nearest node (solve.probe), and stale results marked. Solving from the form shows the result on the Results tab. sample::cantilever is a solvable model for tests and demos. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Simplify the results display (review) One Contour in the plot; the results scene reuses scene::build; a solve shows its result through the engine (ResultsView::for_result) and the UI raises the Results tab when a view appears; the plot's scale and contour values are kept across animation frames; design bodies are tessellated once per design; the first content is framed where the display is rebuilt; field_values in one match; probe reuses results::displacements. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm * Results display for explicit steps: field frames, energy histories The results view works on the engine's step results (static, frequency, explicit): ResultsView.frame and results.frame {frame | time} pick an explicit field frame; the deformed shape (true scale) and contours (element stresses averaged to the nodes, velocity) follow it; animation runs through the frames. The Results panel has a frame slider and plots the kinetic, internal, hourglass and external energies with their values at the frame. sample::impact is a steel bar flying onto a rigid wall.

fix: regenerate docs/features.md (tet meshing is ready since #29) (#32)
Main's CI failed features_page_is_current: #29 marked mesh.tet.generate ready, and the page generated on its branch was out of date once combined with main.
