Lumeira 1.5.1

Changed

• One look for every overlay. Status, counter, error banner, folder bar, slideshow controls, compare pane labels, and the full-screen hint share the same quiet capsule: small secondary text on a thin material, with a slow fade for the ones that come and go.
• Compare pane labels moved to the bottom-left of each pane. They no longer sit under the window's own overlays. The active pane's label carries the folder counter, and its border is a single thin line of accent color.
