- The build now emits public/_headers implementing the embeddability split
(direct-embed pages framable anywhere; staging preview-only) — Netlify/CF
Pages consume it automatically; serving/traefik-embed-headers.yaml is the
proxy-side reference. The contract is auditable in-repo, not just documented.
- README: docs table gains how-to, layouts/README (the SPA machinery), and
docs/architecture; Quickstart gains bun run serve + bun run phone.
