[Placeholder] Sign-in/upgrade flow redesign — pending design tokens

[islandbitcoin]

Placeholder to reserve sprint sequencing. Scope: full sign-in and upgrade intervention redesign per Lori design spec.

Design spec (draft, pending revision): ~/.openclaw/workspace-uiux/DESIGN_SPEC_SIGNIN_UPGRADE.md
Note: spec was written against dark theme, Lori revising for light-first before implementation-ready.

Blocked on:

1. Design tokens shipping (Week 1 of Lori sprint plan)
2. Product decision: Nostr/Chat tab — gate behind Advanced Mode vs. always visible (Dread + Lori to align). Affects nav structure in sign-in spec.

Waiting on Lori to provide updated spec path when ready to link.
