app harness

Run your app against the real window.glslop bridge in the same sandboxed iframe production uses — no publishing, no moderation, no account needed. The apps analog of the shader --dry-run loop: edit → run → screenshot → repeat.

• Reads are live — listShaders/search/getShader hit the real public commons.
• render()/snapshot() are the real injected renderer (compile-check generated shaders here).
• generate() uses your own BYOK key (entered below, kept only in this browser).
• submit() is mocked — it compile-checks and logs the exact payload (incl. the auto-attached generator), but nothing is posted. Test the real submit on the published app.

Headless? Load this page in Playwright, thenawait page.evaluate((html) => window.glslopHarness.load(html), appHtml) and screenshot the iframe. Full reference: /apps-skill.md · guide.
