/* =============================================================================
   v2 stylesheet — compact, graph-first. The map fills the viewport; controls
   (left) and info (right) are collapsible panels toggled from the app bar, so
   the graph can go full-bleed. Controls use accordion sections to stay short.
   No external fonts (CSP: system stack). Legend swatches are classes.
