/* ============================================================
   Hero · The Blueprint
   The first screen is an architect's drawing sheet: warm paper,
   a drafting grid, registration marks, a headline annotated with
   a dimension line, and a title block carrying the facts. The
   Scale Tower (js/hero-blueprint.js) is drawn in ink hairlines on
   the right. On scroll the sheet lifts off into the dark world.

   Every element is visible in its final state by default — the
   entrance (HeroBlueprint.compose/enter) only pre-poses and plays.
