The HUD root gains the tuner and the enlarge overlay, the T/arrows/B/M keys,
and the small amount of session state the onboarding needs: the mercy toast
fires once ever, hatch warnings are remembered per pile.
The fossil reveals the dock from either direction — the relicFound event, or a
loaded save where relics[].found is already true and no event is coming. The
dock lands in the toast stack's corner, so the toasts stand off above it rather
than printing over the dial.
Esc now closes the most-recently-fronted thing first: enlarge, then the held
tool, then panels.
