		These entrypoints avoid pulling in other platform adapters, keeping browser bundles slim and Node installs free from WASM/downloaded assets.

		## Multi-tab role awareness (browser)

		In browsers, UniSQLite elects a single writable host tab for a given database. SQL calls are already transparently forwarded through RPC, but applications may want to run background tasks (sync, persistence/flush, etc.) only on the host tab.

		The browser adapter exposes a lightweight, capability-based role API:

		- `getRole(): "host" \| "participant" \| "unknown"`
		- `subscribeRoleChange(listener): () => void`
		- `waitForRole(role, timeoutMs?): Promise<void>`

		These methods are optional on `UniStoreConnection` for compatibility with other adapters/older versions, so feature-detect them:

		```ts
		import { openStore } from "@loro-dev/unisqlite/browser";

		const db = await openStore({ path: "my.db" });

		if (db.getRole?.() === "host") {
		// Start background sync/persistence only on the host tab.
		}

		const unsubscribe = db.subscribeRoleChange?.((role) => {
		if (role === "host") {
		// Became host.
		} else if (role === "participant") {
		// Lost host.
		} else {
		// "unknown": initializing/closing; treat conservatively.
		}
		});
		```

		Role semantics:

		- `host` means host-ready (safe to run host-only work)
		- `participant` means initialized but not host
		- `unknown` is a transitional state during initialization/close; treat as `participant`

		### Debug logging (browser)

		UniSQLite browser logs are gated by `localStorage.debug` (errors always log). Examples:

		```ts
		// All UniSQLite logs
		localStorage.debug = "unisqlite:*";

		// Only adapter + host election logs
		localStorage.debug = "unisqlite:adapter,unisqlite:host";
		```
