The picture is `lock.look.wallpaper`, or else the wallpaper the colours came from: `matugen/amane.colors` writes its path into the theme file (`wallpaper=`), so it's there after the next wallpaper change. Without either, the colours' gradient. Amane reads PNG and JPEG only.
It redraws for the music's progress, the clock and typing, so it's cheap to draw: the backdrop (the gradient, and the veil over the picture, darker toward the corners, `lock.look.vignette`) is one shader, `src/lock.wgsl`, and every icon goes into one canvas. Measured in a preview on one 1080p monitor: 0.8 ms per frame to submit and present (2.4 ms before), the GPU's render engine half as busy.
Killing the shell does not unlock: Hyprland keeps the session locked and shows its own error screen. Keep a second TTY logged in when trying changes to the lock screen.
