// ── module-uo's client entry point ─────────────────────────────────────────
//
// Core injects `dist/entry.js` as a `<script type="module" src>` before
// `</body>`, this file registers what the module has, and core renders it. The
// normative contract is MODULE_API.md §3.3.
//
// **Registration is synchronous and happens at evaluation time.** Module scripts
// are deferred, so this runs after core's bundle — which is where `window.__rg`
// is published — and before DOMContentLoaded, which is what core waits for
// before its first render. There is no subscription and no late registration: a
// module that registered asynchronously would register after the routes had been
// read, and the symptom is a page that redirects home with nothing logged. That
// bug cost the Phase 2 client PR an afternoon and no unit test in either repo
// can see it, which is why §7.7's browser smoke exists.
//
// So everything below is a plain top-level call, and every page is a static
// import. Lazy-loading the routes would be the natural instinct for a chunk this
// size and it is the one thing this seam cannot have.

//
// Paths are relative to this module's namespace and core prefixes them:
// `/uo/…`, `/admin/uo/…`, `/player/uo/…`. A module cannot write the segment its
// routes hang under however it spells `path`, which is the point.
//
// **These SPA paths changed and the API paths did not.** `/site/shard` is now
// `/uo/shard` and `/admin/shard-ops` is now `/admin/uo/ops` — a clean break with
// no redirects, settled in MODULE_SYSTEM.md §2.7. Every URL in `api.js` is
// byte-identical to the one core called, because §1.2 freezes the API surface
// and the shipped Android app calls seven of these routes.
//
// The admin paths lost their `shard-` prefixes on the way through: under a `/uo/`
// namespace `/admin/uo/shard-visibility` says "shard" twice, and a clean break is
// the only moment that tidy-up is free.
//
// `gate` is core's own RoleGate, applied by core. A module cannot supply an auth
// wrapper — the sidebar and the route table have to agree about who may see what.
