Spatial redesign — rendered screens

Every screen is the real component, fed a ViewModel from a state reached by playing the era — not hand-assembled. Buttons are inert. Build 90e8e68.

Era 0 — the guided first session Landing, the hub, a mostly-unleased base, the guided step Era 1 — the leased base Trading floor, fuller logistics floor, collect in place, the offload confirm

These are mockups, not a playable build. The redesign is not wired into the app yet, so the deployed PWA still shows the tab navigation. Numbering follows docs/client/redesign.md.
