/* ===================================================================
   Departures Tiles + Series View — Phase 3 (rebuild 2026-05-04)
   --------------------------------------------------------------------
   Three states based on body classes:
     (none)                          → lanes mode (legacy departures-browse)
     .dt-tiles-mode                  → tiles landing (overlay shown)
     .dt-tiles-mode.dt-series-active → per-series scoped view

   The legacy lanes/board are completely hidden in tiles mode (both
   landing and series-view). When a series is active, a clean scoped
   panel renders independently — hero + series board + series lane.
   No CSS-filter hacks on existing cards. No Frankenstein.
