- Fire a one-shot ignition (expanding rings, edge pulse, child flares) when a project completes; queue it if the console is closed or on another tab, dropping stale events after 15s
- Add per-tech progress pips on each category tab showing done/in-progress/not-yet states, with a pulse on the active one
- Light up unlocked nodes with an accent glow ring, icon halo, and a stamped seal glyph replacing the plain checkmark
- Add dev harnesses for screenshotting the live completion treatment and verifying the queued-celebration path
