{# THE WORKSPACE SHAPE. `page.html` beside this file is the STANDALONE shape. An app that ships to the app store provides both, and they are not the same template with a different wrapper: page.html extends scitex_ui/standalone_shell.html. It owns the whole document, and the shell it extends is the one that includes the mount marker. index_partial.html THIS file. The workspace shell owns the document; the app is handed a container and renders INTO it. There is no , no , and therefore nowhere to put a marker of its own. The example carried only the standalone half until 2026-09-06, which is why `scitex-app app validate` reported it missing — and the missing half is the one with the harder rules, so its absence removed the part worth teaching. #}

Hello, world

The same app, rendered inside the workspace shell instead of owning the page. Nothing below assumes a URL.
