/* ============================================================================
   Boarding Pass runway — a daily "season" of stamps rendered as a cream ticket
   with a plane on "today". Free track (left) + Boarding Pass Plus track (right).
   Content rules are scoped under .bp-host — a class carried by BOTH the v1
   full-screen overlay and the Departures sheet's Pass pane, so the boarding
   pass renders identically wherever it's mounted (2026-07-28, when the sheet
   swallowed the overlay). Only rules whose subject is the overlay ELEMENT
   itself still use #boarding-pass-overlay. Classes are bp- prefixed to avoid
   collisions with the rest of the app. See project_boarding_pass_runway memory.
