   Empty-leg corridor — /empty-leg-flights/{slug}/
   Direction B "Utility": sticky alert rail, stats band, pure-CSS
   pricing chart, rules cards, dormant snapshot, FAQ accordion.
   Design contract: .planning/design/empty-leg-corridor/ (mockup +
   README). Tokens only — no raw hex, px sizes only where the
   mockup fixes geometry (bar height, caret square).
   Enqueued conditionally on is_singular('corridor') — stays out
   of the inlined critical-CSS budget (D-26).
