/* Gallery Page Styles
   Rebuilt 30 Sep 2026 (js/gallery.js). The picture sits in a FIXED 16:9
   frame - it never takes its size from the picture any more, so a tall or
   odd-shaped picture no longer makes the whole box (and the page under it)
   jump. The picture is shown whole, over a blurred copy of itself that
   fills the edges. The controls moved out of the picture into a bar under
   it, using the site's standard 40px buttons. */
