The Go binary is now a data-layer service only. The `/` catch-all that
served an embedded SPA shell is gone; v1.3.0 keeps just the endpoints
the FE depends on:
- /v1/* — indexer + blockscout-compat REST APIs
- /health — health probe
- /envs.js — runtime brand/chain config (window.ENV)
- /icon.svg, /logo.svg — per-host brand SVGs (overlay-friendly)
- /icon-{slug}.svg, /logo-{slug}.svg — extra named brand assets
Every other path returns 404 so the IngressRoute hands it off to the
per-brand Blockscout FE Deployment (ghcr.io/{brand-org}/explore-{env}).
Concrete deltas:
- frontend.go: drop handleSPA, writeIndex, f.index; replace with
handleNamedBrandAsset + brandAssetNames discovery
- frontend_test.go: TestFrontendNoSPA + TestFrontendBrandAssetsServed
replace the index-html overlay tests
- Dockerfile: drop Next.js frontend build stage; runtime image is just
the Go binary + brand SVGs (no embedded HTML)
- static/index.html: removed (60-byte placeholder)
The per-brand FE Deployments + IngressRoute patches that complete this
split live in the cluster (lux-mainnet + lux-testnet namespaces). Source
of the FE images: luxfi/explore via Dockerfile.branded.

# As of v1.3.0 the Go binary is API-only — it serves /v1/* (indexer +

# blockscout-compat REST), /health, /envs.js, and per-host brand SVGs.

# Every other path returns 404 and the IngressRoute routes it to the

# per-brand Blockscout FE Deployment (ghcr.io/{brand-org}/explore-{env}).

# Built from luxfi/explore via Dockerfile.branded — see ~/work/lux/explore.
