/* /explorer/assets/css/drift-analytics.css — D32e-impl-1
 *
 * Drift Analytics panel styling. The panel mounts inside the existing
 * Runtime Evidence letterbox (#gmap-evidence-tray); these rules style
 * the new content layout (series rail on the left, chart on the right,
 * polished header) without redesigning the tray shell.
 *
 * All colours route through tokens defined in tokens.css so dark theme
 * + future light theme both work.
 */

/* Panel grid layout — left rail + chart, with a header strip on top.
 * Mounted inside .gmap-evidence-tray-panel which is itself inside the
 * collapse-aware tray body, so heights are driven by the tray.
