/* Section "eserler" — "The works develop in a gallery."
 * A curved, horizontally-moving hall of framed works: each starts as a gold
 * blueprint and a gold scan-line sweeps it into full colour as it reaches the
 * centre, while a shared year odometer rolls between neighbouring years.
 * Everything driven by js/sections/eserler.js is a pure function of scroll
 * progress. All selectors scoped under .s-eserler. */
