The /try/ client uses phone/session.mjs and the shared AC engine. The first release makes JavaScript pieces using hosted AC braincells, publishes edits to the signed-in handle and embeds the public piece. It does not run a local CLI.

npm ci --prefix easel/web
node easel/web/build.mjs
node easel/web/serve.mjs
# http://localhost:8771/try/

The build writes only to system/public/aesel/try/ (or a supplied output directory). It bundles explicit browser shims and guides; it never serves the repository or exposes a development token endpoint. Its only build dependency is pinned esbuild. Build outputs are ignored by git.

Auth0 uses the existing AC SPA client, LVdZaMbyXctkGfZDnpzDATB5nR0ZhmMt, at hi.aesthetic.computer, with the existing vendored Auth0 SPA SDK and PKCE. Append these settings without replacing other AC URLs:

Setting	Production	Local
Allowed Callback URLs	`https://aesel.app/try/`	`http://localhost:8771/try/`
Allowed Logout URLs	`https://aesel.app/try/`	`http://localhost:8771/try/`
Allowed Web Origins	`https://aesel.app`	`http://localhost:8771`
Allowed Origins (CORS)	`https://aesel.app`	`http://localhost:8771`

Auth0 owns token storage and refresh. Engine credentials stay in memory. Drafts, conversation context and the last-opened piece are stored separately per Auth0 subject in this browser's localStorage. They survive sign-out but are not synced between computers. Download source before clearing browser data. Model output is rendered as text; preview code runs on the separate AC origin in a sandboxed iframe. The gate discloses public publishing and existing staff access.

After committing and pushing to main, run bash easel/web/deploy.sh. It builds from that pushed commit on lith, then atomically switches the /try/ symlink to the new release. It does not deploy other working-tree changes or restart the monolith. The existing aesel.app Caddy site serves the result. Prior releases remain in /opt/ac/.aesel-web-releases/; try/build.json identifies the revision. A regular monolith deployment does not rebuild this client; run this script again when its shared engine dependencies change.

Validation:

node --test easel/web/storage.test.mjs easel/test/phone-session.test.mjs easel/test/phone-credits.test.mjs
node easel/web/browser.test.mjs

The browser test needs the local server and installed Chrome. It uses the real bundle and agent loop with mocked authentication, inference and uploads. It checks saved conversations, two tool rounds, publication and preview wiring, account isolation, escaping, logout and mobile layout. It does not prove live Auth0, live inference or rendering on older browsers. Browser build targets: Chrome 90, Firefox 91 and Safari 15.6; actual oldest-device support still needs device testing, including the AC runtime inside the preview.

Only pieces are supported initially. Native preview capture, local files, other media and vendor CLI subscriptions remain desktop capabilities.
