Prototype Explore nf-2jj ← Beads

Twinned from https://github.com/cfsh/ninefold/issues/907 by tools/beads/import_github.py's reconcile pass.

Prototyping scratchpad for games/explore, per games/explore/docs/GAME_PROMPT.md. Session-continuity notes for /root/nf/devs/argo (pairing worktree, rev:off).

Sequencing (agreed in chat, 2026-08-14)

1. Core space-travel loop, single planet. - 1a. interact + ship interior + surface<->ship doors — merged (#852, #862) - 1b. control panel modal (takeoff/stay) + orbital scene (land/leave-orbit) + the round trip back down — in progress, branch feat/explore-takeoff-orbit 2. Solar system scene + Lava/Icy planets — not started 3. Building + interior room — not started 4. Polish pass (real focus widget everywhere, serializable GameState) — not started

Backlog, not yet: real building-exterior sprite, building interior content, more climates, procedurally generated solar system layout.

Current chunk (1b)

Adding: - ExploreMenu (pure) + ExploreMenuOverlay (Godot) — the small custom focus widget GAME_PROMPT.md asks for, reused by every modal/menu in the game. - Control panel interact -> takeoff/stay modal -> orbital scene. - Orbital scene: globe + ship + land/leave-orbit menu. Land -> ship interior. Leave orbit has nowhere to go yet (no solar system scene) — routes to main menu for now, flagged as a stub in code, real destination lands in chunk 2.
