- Charts render as single SVGs with axis labels inside the viewBox,
replacing the stretched plot + HTML overlay labels
- Rolling ranges end at now, t0 aligned to UTC day; bucket size follows
the window (6h up to 31 days) so "all" at its 30-day minimum renders
identically to "month"
- X labels always centered on their true position; no edge-align shifting
- rangeWindow simplified to rolling spans ending at now
- TransitionGraph "all" visual scale floored at the 30-day plot minimum
