Initial commit — Station 0 vertical slice in progress
Includes full design documentation (ARCHITECTURE, DESIGN_NOTES, CONTENT_SPEC, PRODUCTION_NOTES) and active Godot 4 / GDScript codebase. Core systems built: player, floor generation, room system, enemy base, body part upgrades, run manager, save system, HUD, EventBus.
