Upstream had 1112 Turbopack errors from Chakra UI v3 API changes
accumulated during the old merge approach. Instead of fixing them,
reset to clean upstream/main and re-apply only Lux customizations:
- .github/workflows/build-lux.yml (CI -> ghcr.io/luxfi/explore)
- configs/envs/.env.lux (mainnet chain 96369)
- configs/envs/.env.lux_testnet (testnet chain 96368)
- LLM.md, CLAUDE.md, AGENTS.md (AI docs)
- cspell.jsonc: add luxfi to word list
All branding is via env vars at deploy time. Zero upstream code modified.
Build verified: pnpm lint:tsc (0 errors), pnpm build (success).
