Function: useChartChrome()
useChartChrome(
ref):ChartChrome
Resolve the chart chrome for ref’s element and keep it current as
the theme changes.
Two triggers, matching the two ways AppKit’s stylesheet switches
themes: an explicit .dark / .light class (watched with a
MutationObserver on the document root, which is where hosts toggle
it) and the OS preference that :root:not(.light) falls back to
(watched with matchMedia). The resolved value is compared
structurally before being stored, so an unrelated attribute change
does not hand callers a new object and re-render every chart.
Returns LIGHT_CHART_CHROME on the first render - the effect that reads the real tokens runs after mount, by which point the chart itself is usually still long-polling its spec.
