- Removed ScreenManager idle sleep entirely (constructor no longer starts
the idle monitor, setIdleTimeout is now a no-op, unused fields and the
private startIdleMonitor method removed). Display never sleeps; the
photo frame provides the idle visual instead.
- DashboardContent now uses flex-row: calendar 90% wide, todo 10% wide.
- After 5 min of no touch/motion, dashboard hides behind a fullscreen
photo slideshow with centered time and date overlay
- Photos loaded from PHOTOS_PATH env var (defaults to ~/Pictures/dashboard)
via IPC + file:// URLs; traversal-guarded, recursive up to 2 levels
- Motion or touch exits idle back to dashboard
- Theme repainted warm cream / sage / stone ink with Nunito font and
rounded cards; dark tokens kept so component classes still resolve
- Adds PHOTO_FRAME.md with Samba cifs mount + systemd env instructions
