nav-bar.css (after gantry.css) draws the bargraph, caret, indicator,
chapter drop and ripple, route glints, brake, self-test and shimmer in
LCD pixels under gantry's mask, and masks the wave to the lower bezel.
Rules hang off html:root, the same weight the preview attribute had, so
they still beat gantry.css.
useNavBarSignals mirrors the speedometer, drive controls and chapter
onto the bar, writing only on change; the per-frame speed pair goes on
the LCD and wave rather than the nav, which keeps the per-frame restyle
small. SiteNavigation renders just the parts the bar uses.
A lazy chunk (journey/nav-wave.ts) that draws the bar's wave: a calm
ribbon at cruise, a spectrum at speed, with a hue cycle near the top of
the dial. It follows the chapter's accent and the dawn, repaints at once
on resize, and draws one still frame under reduced motion. Budgeted as a
deferred chunk.
One shared window (journey/card-gaps.ts, CARD_GAP) describes the open road
after each chapter's panel in section-local progress; the district relight
and cutover, the last yard lift and the relay station's beams now key off
it instead of their own numbers, and the chapter margin widens from 44vh
to 48vh so the gap reads as a stretch of road. Unit tests prove every
payoff's peak sits inside the window for every chapter span.
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.
