    Chat surface (Phase 1 bridge).
    Server renders the page shell with full SPA scaffold.
    Existing SPA JS (app.js, ui-core.js, chat.js, etc.) populates
    these pre-built DOM elements with data.

    v0.22.6 fix: The original index.html contained the full scaffold
    (1,296 lines). When it was replaced with a redirect stub, this
    template needed the scaffold — but it was shipped empty.
    This template restores the required DOM structure.
