Every half hour the page fetches its own address past the browser's cache; when it loads
another content-hashed build of the app than the running one, the status bar offers "Reload
to update" (the page's unsaved-changes question still guards the reload). Rust only, no
service worker: the browser build has no other update path and none of the desktop's
download code.

The window checks at start-up at most once a day when automatic checks are on (Settings and
the first run's question), never while that question is open and never without a host, so the
browser and tests make no network call. A newer release shows a quiet notice in the status bar
("FieldCraft X is available — What's new · Install · Skip"); Install downloads and verifies
through the host, then asks to restart, saving or asking about unsaved changes first, and the
host swaps the release in after the window closes. A .deb/.rpm install offers the system's
installer and the command instead. Skip this version is kept in the preferences.

The first run asks whether to share anonymous usage (only when the host
says this run may), the answer and a random install id are kept in the
preferences, and Help › Settings… changes it. Commands are counted by
where they came from (ui, palette, script; mcp when the MCP server says
so), and cancelled forms and clicks on commands that cannot run yet are
recorded. The preferences go through a PrefsStore (a file, or the
browser's storage). Control channel: ui.settings, ui.prompt answers.

A datum plane is drawn as the model's extent within it (where it cuts the
model's box, in the plane's axes) plus a 5 % margin, a datum axis along the

Fit, Home, the standard views and headless pictures frame the model

the window's commands (background jobs included) and every control

Boundary condition, load and interaction symbols are wireframes (thin lines,
no shaded cones), so they never hide the mesh or a contour plot:
- a crossed wire triangle per constrained translation, tip on the node,
coming from outside the part where the set's faces say which side that is;
a held rotation adds a smaller triangle behind it (the double mark); fixed
shows all three axes, a symmetry plane only its normal;
- forces as open-headed arrows ending on the node, as long as four support
units at one place and 2.5 over a set, so loads and supports stay in
proportion (#78); moments as an axis line and a right-handed curved arrow
(#79); contact and tie surfaces as small squares on their faces;
- a constant size on screen at any zoom (#80): the symbol unit is the size
setting (View > Symbol size, `ui.set {symbol_size}`, 14 pt by default)
times the model length a pixel spans, rounded to a quarter of a doubling;
- spread evenly on a grid a few symbol units across, so their density follows
the screen, never more than 400 per definition;
- a layer of their own on the desktop (GPU and CPU): zooming rebuilds and
uploads the symbols only, never the mesh's scene; framing leaves them out;
- colour per kind from the theme's tokens (a new contact colour), and the
definition selected in the browser drawn in the selection colour, wider;
- depth-tested against the model with the line bias that keeps them on their
own surface; a load at a reference point or a single node and a reference
point's cross are drawn over the part (#78).
Headless pictures (MCP screenshot, `ui.render`) frame the camera first and
draw the symbols at the default size for it.

A scene's `on_top` lines are drawn after every depth-tested layer, over the
model, so a concentrated load at a point inside the part can be seen from any
side (#78). `render_layers` takes a list of overlays (the setup's symbols and
the selection highlight become separate layers), and draws every layer's
labels. `Camera::length_per_pixel` is the model length a pixel spans at the
target: the scale symbols of a fixed screen size are drawn at.

An orbit turns about the model point under the press (the pick ray's
first hit on the plot, the mesh or the design), or the centre of what is
drawn when it starts on empty space, keeps that point still on screen and
marks it while orbiting. The wheel and a pinch zoom toward the point
under the cursor; the wheel's delta is read as it arrives, so a notch
zooms in full in orthographic and perspective views alike (#273).
Mouse presets and reverse zoom come from SolidCraft (prefs.rs NavPreset,
NAV_PRESETS; MIT OR Apache-2.0): FieldCraft's own (left drag per the
navigation bar) stays the default, Ctrl + left drag from empty space
orbits in every preset. They are chosen in the display menu, settable
with ui.set and kept in prefs.json beside recent.json (the browser build
keeps them for the page's run); an older prefs.json still loads.

Every fit frames what is drawn (the deformed shape and the setup's symbols
included) with Camera::fit_in in the part of the viewport the overlays
leave free: the results legend, the selection bar, the gizmo and the
navigation bar (framing::free_part). Standard views fit too, so a long
beam's front view keeps both ends (#147); fit and home leave the legend
clear (#76). The view frames itself in the home view when another model,
sample or design is opened (Session::opened; the same design opened again
after an edit keeps the camera) (#233), and when results come up with part
of the model out of sight (#223). ui.inspect's layout reports the legend.

Zoomed in on the hex20 crank arm, the element edges and the shaded faces
did not meet (#260). The mesh is conforming; the display drew each hex20
face and edge as straight chords between corners while the mid-side
nodes lie on the curved surface (up to 0.44 mm off the chord at 3 mm),
and drew the geometry's face boundaries from the design tessellation,
off both.
Now a quadratic face is cut into triangles whose vertices are its
corners and mid-side nodes, each edge is drawn as its two halves, and
over the mesh the geometry's edges (and a hovered design edge) are drawn
as the element edges on geometry edges (`DisplayEdge::feature`), so
faces, edges, feature lines and the highlight share their vertices.
