// ripple/ui.js — the server-rendered product UI for the ripple plugin.

// One self-contained HTML document (zero deps, zero build, forge-style):

// an app shell over the plugin's JSON api. Sign-in mints a pod bearer from

// the host IdP (/idp/credentials — with account creation via /idp/register),

// so the UI needs no pasted tokens; the bearer lives in localStorage.

// Client code deliberately avoids template literals — the whole document is

// one server-side template string, so client JS sticks to quotes + concat.
