Bumps chip buttons h-6→h-8 with text-xs and ring-1 borders so active/inactive
states are clearly distinct at VNC/remote scale. Save & Apply bumped to h-10
text-sm. Fixes: /50 opacity modifier in class: directives (uses class expression
instead), stale svelte-ignore comments replaced with onkeydown handlers, each
block key added. Documents wallpaper repeat-apply macOS caching bug in TODO with
workaround and fix location (Electron temp filename).
