/* =====================================================================
   ROOFLINE SET-PIECE  ("From bare ridge to a finished roof")
   ---------------------------------------------------------------------
   A pinned stage. As the page scrolls through a tall track, a roof draws
   itself: ridge line first, then the rake + walls as a silhouette, then
   the roof TILES sequence on course-by-course (eave -> ridge), then it
   crossfades to a solid tiled roof in the brand palette and the orange
   ridge cap drops in.

   Mechanic (lifted from the approved Ironbark engine, prefixed .rl-):
   a tall .rl-track wraps a position:sticky .rl-stage. ONE rAF-gated
   passive scroll handler reads track.getBoundingClientRect() once per
   frame and writes a single 0..1 --rl-p on the section. Linework draws
   via stroke-dasharray/offset; tiles + solid + cap read clamp() windows
   on --rl-p. GPU-cheap: transform/opacity/stroke only.

   Reduced-motion AND .no-js collapse the track to height:auto, unpin the
   stage, and force --rl-p:1 (the finished, fully tiled roof).
