Make orbit/pan/select mouse bindings pure data owned by ViewportCore so both
hosts and every preset share one source of truth, and add a "Web" preset. This
rounds out the matrix: the desktop gains a web-style scheme and the web inherits
all presets, with no per-platform hardcoding.
- Core: NavBindings { orbit, pan, select button + modifier } + setNavPreset
("blender" default | "rhino" | "revit" | "web") + navBindings(). Select is
preset-driven too (was hardcoded LMB) so "web" moves it to RMB. web = orbit
LMB, pan MMB, select RMB (LMB drag orbits with no click/drag ambiguity; RMB
click-selects / drag-marquees). NavMod uses "Plain" not "None" (X11 #defines
None to 0L).
- Desktop ViewportWindow: applyNavPreset sources the core table (mapped to Qt);
marquee-arm / single-pick dispatch keys off select_button_. Default stays
blender → no behaviour change.
- Desktop config: AppSettings::NavPreset gains Web + navPresetName(); the
Settings dialog lists it. This also FIXES a pre-existing gap — the preset combo
was persisted but never applied (only WGPU_NAV_PRESET env worked). MainWindow
now applies the persisted preset at startup (env override still wins) and live
on navPresetChanged, so all four presets actually work from the dialog.
- Web main_web: classifyPress routes the pressed button through navBindings()
(orbit/pan/select), defaulting to the "web" preset; context menu already
suppressed so RMB is free.
Tests: setNavPreset table (Catch2, 123 total); web smoke select tests use RMB.
BonsaiViewer builds; 9/9 web smoke.

Coverage had lagged the recent feature work. Add both layers:
- test_viewport_camera (Catch2, headless): constructs ViewportCore with a mock
ViewportHost — construction/teardown touch no GPU (the wgpu teardown lives in
releaseWgpuModelGpuData, only reached with models loaded), and the camera ops
are pure — so it unit-tests the SHARED fly math fast and deterministically:
flyMove (forward step, 5x boost, opposing-key cancel, dt clamp, QE along +Z,
degenerate-pitch stays finite), flyLook (turn-in-place pins the eye, pitch
clamp), flyAdjustSpeed (x1.25/notch, [0.05,1000] clamp), toggleXray, and
hideSelected/showAll. Links the built IfcViewerCore (ViewportCore.cpp is the
monster TU that can't compile standalone). +9 cases → 122 desktop.
- smoke.spec.mjs (Playwright): fly (enter → W moves the camera → Esc exits),
x-ray (toggle translucency on/off), and hide-after-pick, driving the exported
C hooks end-to-end. +3 cases → 9 web.
