Accessibly — Phase 1 MVP

In-house accessibility preferences widget. This Next.js app serves the panel UI, the embed bootstrap, per-site config, and the telemetry endpoint.

• Demo host page — loads the widget end-to-end via the embed tag.
• Panel UI — the iframe contents (normally framed, not opened directly).
• /api/config?site=default — per-site config.
• /api/health — telemetry endpoint (GET shows the recent log).

See DEV.md / the README for how to run locally.
