Moves every solidcraft-* rev and the truck/egui-wgpu patches (same list upstream) from
de1479029dd6 to a629236650c4. Extrude gained a 'thin' option; the sample plate keeps a
solid extrude (thin: None). THIRD-PARTY-LICENSES.txt regenerated (solidcraft 0.8.0 -> 0.11.0).

The end-to-end demo met a raw-CDT sliver that the validity gate accepted (exactly positive) and
the solver refused. Now:
- One validity criterion, `fieldcraft_model::admissible_jacobian` (normalized Jacobian above
1e-12), used by the implicit solver (fem `positive_inverse`), the explicit tet4/hex8
kinematics and the mesh gate, which proves it on the whole element (tet4: the solvers' own
Jacobian; curved kinds: a Bernstein floor), so whatever passes the gate passes the solvers.
- CDT rounding repaired by flips on the rounded mesh (Diazzi et al. 2023 §5.1) instead of the
±2-ulp nudge.
- `fieldcraft-mesh::tet`: a mutable tetrahedral complex whose every change is a checked
replacement (positive and admissible tetrahedra, faces matched with opposite orientation) with
an exact undo log; edge removal (Klincsek), multi-face removal, Delaunay insertion with
boundary faces, edge collapse; a curvature- and thickness-graded size field; constrained
Delaunay refinement with encroachment splits; ODT smoothing; the Klingner–Shewchuk schedule;
boundary vertices moved onto the exact B-rep surfaces at the end; tet10 with mid-edge nodes on
the geometry.
- `mesh.tet.generate` gains size, order, quality, quality_target, curvature_angle, grading,
max_passes, max_points and reports the CDT's and the mesh's quality; `solve.probe` takes a set
and reports its largest von Mises stress.
- Oracle cases filleted-bracket-fillet-stress(-coarse): the fillet's peak von Mises stress on
tet10 meshes of 2k and 13.5k elements, 213.3 MPa (a four-level study stays within 1.8%); the
CDT cases keep the raw tetrahedralization.
- Corpus quality columns: all 20 valid parts mesh and pass the gate.

* Native file pickers, background opening, drag and drop and recent files
Open (models, SolidCraft designs and tagged meshes in one picker), Save, Save As, Write
Deck and Recover go through the host's file pickers (rfd in the desktop app, injected as
Services so the UI crate stays portable and tests answer them). Files open on a copy of the
session in a worker thread and replace it only on success; files dropped on the window or
named on the command line open the same way. A recent-files list, an unsaved-changes prompt,
Cmd/Ctrl+O/S/Shift+S. Programmatic calls never open a picker: ui.start opens the form.

* Samples and one-click Solve: results reachable from the window
file.sample {name} opens a ready-to-run sample (the two parts, the cantilever with static and
frequency steps, the bar impact) in place of the model; solve.run solves every step in order.
Help > Samples, the empty viewport's start screen and the Tools > Samples entry open them
(asking first over unsaved changes); Solve runs in the background like a file opening and the
Results tab comes up. --sample [parts|cantilever|impact] on the command line.

* The Craft-family shell: title bar, workspace ribbon, browser, context panel, timeline
The window now follows SolidCraft's and VectorCraft's layout and themes:
- title bar with the mark, quick actions (File menu, save, undo, redo, Solve, search,
theme, help), the model's document tab and the version; integrated under the macOS
traffic lights, own caption buttons and resize zones elsewhere (titlebar.rs);
- workspaces (Prepare, Model, Analysis, Results) with their tabs, and panels of icon
buttons whose labelled drop-downs list the whole catalogue, coming-soon entries greyed
with their milestone; panels collapse, then go into a » menu, when narrow;
- the browser: geometry and mesh with eye toggles, definitions with counts, results;
- no permanent Commands list: command search (S, Cmd/Ctrl+K) and a command line;
- the context panel on the right only with context: the command form, results controls,
the selected definition's properties with Edit and Delete;
- navigation bar and orientation gizmo in the viewport; the journal timeline at the bottom
with undo positions;
- SolidCraft's light and dark tokens; craft-ui (IconButton, Tab, WidgetPalette).
Menus and the search are view state (ui.set {menu, palette}), so captures show them.

offscreen captures without fade-in, ui.start runs in-window file actions (samples, recover,
solve) but never a native picker, ui.select. Control protocol, architecture, ROADMAP, AGENTS
and ATTRIBUTION updated; THIRD-PARTY-LICENSES.txt with craft-ui and rfd.

* Title bar mark from the application icon; fluid steps and domains in the shell
The title bar draws the app icon's bracket (assets/app-icon/icon-small.svg's faces) as
SolidCraft draws its mark; the window keeps its title-bar flags after the rebase.
solve.run solves fluid steps too (solve.fluid); the browser lists fluid domains.

Claude-Session: https://claude.ai/code/session_01NmAttHhUZTokgPeEJia8sm
* Simplify: cached per-frame data, one command per timeline roll, workspace setters
- Icon textures are kept per pixel size (the shell draws several sizes a frame; the cache
used to clear on every size change and rasterise again).
- Opening a model or recovering one starts from an empty session instead of copying the
current one; the replaced session is freed off the window thread.
- Element counts, timeline items, search results and the selected definition's properties
are cached until what they show changes; timeline tooltips are built on hover; long lists
in properties are summarised.
- edit.undo and edit.redo take a count: a timeline click is one command.
- solve.run dispatches on the step's procedure (no string round trip) and reports its name.
- The workspace and tab change together through UiState::select_tab/select_workspace
(ui.set {workspace} alone now sticks); no per-frame syncing.
- One busy guard, Kind::verbs, a fit flag for background jobs, ModelApp::home_view, the title
bar's actions as an enum, dead code removed.

* Title bar: Solve and tools at the right end; no traffic-light inset in full screen
The owner's feedback on the title bar: Solve, search, theme and help sit at its right end
before the version; on macOS the left group (mark, name, quick actions) moves into the
traffic lights' room in full screen, where there are none, and back when leaving it. The
layout is a pure function (bar_layout) tested for both states, narrow windows and custom
caption buttons. ui.fullscreen {on} for agents.

* Caps labels in Inter SemiBold
egui has no bold weight of its default font, so the ribbon's tabs and panel labels, the
workspace switcher and its menu, menu headings, the browser header, the context panel's
headers and the Solve label were thin, especially in the light theme. They now use a label
font family: Inter SemiBold 4.1 (SIL OFL 1.1, unmodified, fonts/OFL.txt, ATTRIBUTION.md),
with egui's fonts as fallback, installed with the theme on the live and offscreen contexts.
theme::label_font falls back to the default font until the family is bound (fonts take
effect from the next pass), so nothing can panic. Panels widen to their label's longest word.

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.

* modelcraft-fem: element kernels for tet4, tet10, hex8 (full, incompatible modes), hex20 (full, reduced)
Shape functions, Gauss and conical-product quadrature, stiffness, consistent and HRZ-lumped
mass, body forces, consistent pressure loads on faces, integration-point stresses and their
least-squares extrapolation to nodes, isotropic and orthotropic elasticity. The element table is
one row per kind, so wedges, shells and beams are added locally.

* modelcraft-solver: linear static and frequency analysis with an analytic verification suite
Assembly from the resolved model on the node graph, boundary conditions by elimination,
consistent pressure, gravity and body-force loads, nested-dissection ordering, sparse up-looking
Cholesky with a factor-size cap, reactions, integration-point and nodal-averaged stresses, von
Mises; shift-invert block Lanczos with full reorthogonalization for natural modes, participation
and effective mass. ADR 0001 records the own-linear-algebra decision (determinism, wasm).
Verified against closed forms: displacement and traction patch tests for every element, cantilever
tip deflection (Timoshenko) with convergence rates, Lamé cylinder, Kirsch hole (Kt -> 3),
cantilever and free-free beam frequencies with six rigid-body modes.

Results are stored per step, restored on a failed command and cleared when the model changes.
Caps (degrees of freedom, factor entries, Lanczos vectors) may only be lowered; hostile parameters
are tested against a solvable session.

* Simplify the solver: shared face integration, block assembly, cached extrapolation
- model: one face integrator (nodal::face_normal_weights) for tractions and pressures
- fem: mid-side tables from ElementKind::edges, orthotropic via inverse3, symmetric
accumulation without a symmetrize pass, incompatible-mode recovery without K_uu, model's
coordinate check, dead table rows removed
- solver: one pattern search per node pair (block, scalar and diagonal adds), extrapolation built
once per element type, reactions from the prescribed rows only, matrices dropped after
restriction, the free-body shift keyed on the factorization error, step selection in the solver,
Error::Element naming the element
- engine: the solver owns the default step and the shift check; the model comparison runs once

* modelcraft-io: the .modelcraft file (modelcraft/1), atomic writes, autosave storage
A stored ZIP of a manifest (format tag, geometry sources with SHA-256,
part sizes and hashes), the model definition as stable pretty JSON, the
mesh and geometry tags in a compact binary part, and the journal one
command per line. Reading caps every size, checks every checksum and
replays the model through its checked methods. Model::without_mesh and
empty mesh fields left out of the model's JSON; geometry::read_file.

CommandSpec gains a kind: Model commands are journalled and become undo

with content hashes and reopened on file.open (missing or changed files
are warnings). Desktop app autosaves every 30 s and reports recoverable
models; Ctrl/Cmd+Z and Shift+Z/Y undo and redo.

* render: simplify the display mesh (sorted face keys over maps, no unused fields)
Interior faces are found by sorting fixed-size face keys instead of a BTreeMap of Vecs, edges
are deduplicated by sort, and each element's corners are looked up once. Drops the unused
`element` fields on DisplayTri/DisplayLine, the unused Mat4::IDENTITY and corner_count, and
hoists the line colour out of the raster loop.

* viewport: split GPU geometry into batches within the buffer limit; refuse oversized CPU renders
A mesh with a few million boundary triangles made one vertex buffer larger than the device's
max_buffer_size (256 MiB under the limits eframe requests), and wgpu's default error handler
panicked. Geometry is now uploaded in batches of whole primitives, each at most 128 MiB and the
device limit, and all are drawn. A device error handler logs errors and shows them in the status
bar instead of panicking.
The CPU renderer refuses sizes over 8192 per side or 16 MP, and scenes over 20 million
primitives, with an error, and allocates its buffers fallibly. ui.render reports a size out of
range instead of clamping it; the CPU viewport fits a large window into the limit.

docs/formats/tagged-mesh.md defines the exchange: 3MF Core with an optional
ft:face attribute per triangle (and ft:faces per object) in a ModelCraft
namespace. modelcraft_geometry::tagged_mesh::read_3mf reads it from bytes
(wasm), capping every size and count and range-checking every index and
coordinate. geometry.import.mesh adds the surfaces to the session, which keeps
them beside the open design and restores them when a command fails.

* geometry: open .solidcraft designs, rebuild them and keep persistent face names
open_design(bytes) reads a design (container or JSON) with solidcraft-io, rebuilds its
timeline with solidcraft-doc and returns its bodies; each Shape carries SolidCraft's
persistent face names by B-rep face index, so a face keeps its name through a parameter
edit. sample::plate_design builds a parametric test plate in code.

in-memory files). Drops the duplicate size check, simplifies the sample sketch and the
