/* ==========================================================================
   ENDEVELOPMENT · mougins.css — the flight through Villa 9, its two
   pictures, the rail of its steps and the 360° visit.
   --------------------------------------------------------------------------
   Loaded by mougins.html only, after styles.css, with the same rules:
   everything outside `.is-*` states describes the static page (no script,
   or prefers-reduced-motion); mougins.js adds `.is-scrub` and the other
   states. Only transform and opacity move; the one clip-path that changes
   is the 360° visit's window while it opens and closes.
