/* ─── ANIMATED OVERLAYS ───────────────────────────────────────── */
/*
 * Overlays are SVG <line> elements cloned from base paths and appended
 * by map.js. _clearActive() removes them from the DOM entirely —
 * no stale class state possible.
 *
 * One-way:    one overlay per segment, full stroke-width, one direction.
 * Round trip: two overlays per segment, each at half stroke-width,
 *             flowing in opposite directions simultaneously.
 *             The half-width makes the two streams visually distinct lanes.
 *
 * Jitter fix: explicit from/to keyframes + per-segment animation-delay
 *             staggering prevents all segments resetting simultaneously.
