/* ============================================================================
   Ducey's on the Lake — version 4, "The Pass"
   ----------------------------------------------------------------------------
   A hard vertical seam held down the entire page. Left half is a pinned
   photographic panel that swaps as you move through the sections; right half
   scrolls. The restaurant name straddles the seam at the top, half in each
   panel, which is the one moment the two sides are treated as one surface.

   Reference: Face Formula's split wordmark, Faculty Department's pinned-left /
   scrolling-right column.

   Palette stays in the blue but goes colder than v3: steel and slate rather
   than warm navy, with gold as the only warm thing on the page. No cream, no
   paper — the brief was to drop the white.

   Type: Newsreader (display, real italics) and Work Sans. Neither appears in
   v1, v2 or v3.
