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.
