A 240-degree SVG dial with a spring needle, three-digit readout, unit
label, warning lamp (BRAKE / OVERDRIVE / ENGINE OFF), trip odometer and
gear chip, driven by the journey's own frame loop from the scroll drive,
route progress, navigator state, scene ignition and the high beam. Hover
or focus shows route, exit and time on the road; a click toggles km/h
and mph (remembered). The model and DOM driver load as a lazy chunk so
the initial bundle grows by about 1.3 kB gzipped; reduced motion snaps
the readout, and the bay hides below 1280px.
I warm the world's programs with renderer.compileAsync() at the end of the
async build, with the composer's scene target bound so tone mapping and
output colour space key the same programs the composer draws with, and with
hidden subtrees revealed so the light count matches the frame-0 warm render.
The wait is capped at 2.5 s; the warm render stays as the safety net for the
post passes, texture uploads and anything a slow or extension-less driver
left. Test builds report renderer.info.programs, and a browser spec pins zero
program growth after frame 0.
On the Intel ARL laptop the frame-0 task drops from ~1.74 s to ~0.34 s with a
pixel-identical first frame; measurements in
docs/overnight/compile-async-results.md.
The sign closes in over the road on a gantry truss, arcs into a wider
window and hands off to a flat 2D plate that mirrors its face; content
steps aside for the interlude and rises after. The bay keeps sound and
settings; volume and Pause motion move into the settings popover.
The top bar becomes a steel gantry. Its centre window is a mask cut-out the
3D exit sign docks into; between signs the window shows the dash read-out.
The drive controls move into the right bay, and the reading viewport is
clipped at the beam, so the empty band under the bar is gone.
Exercise sign state updates and composition together, covering responsive placement, grounding, label reuse, resource ownership, and departure motion. Update poster and visual-model expectations while retaining behavioral checks.
Validation: 46 focused tests passed before commit. The preceding full build:preview run passed all 673 tests plus typecheck, builds, prerender, artifact verification, and transfer budgets.
Add the approved name animation, rounded docking navigation, localized keyboard focus cue, unified builds card, and destination copy hierarchy.
Introduce lightweight one-shot meteors and a sun ring that repeats every three seconds at Contact. Open the email action in a separate browsing context. Preserve reduced-motion behavior and keep private handoff and visual-check artifacts out of version control.
Validation: 649 tests passed; all 20 failures in world-models and SceneCanvas reproduce on baseline 103427f. Typecheck, artifact verification, and transfer budgets passed. Client/SSR preview build passed before this commit. Existing baseline test failures remain unchanged.
