The uploaded source lives under the `artifacts/` prefix in this val's\nproject-scoped blob storage. New remixes therefore start with isolated data.\n\n## Security model\n\nArtifacts are untrusted content, including Markdown that contains raw HTML:\n\n- They render in an iframe without `allow-same-origin`. JavaScript can run, but\n it cannot read the app's cookies or call app routes as the viewer.\n- `/a/:id/raw` also sends `Content-Security-Policy: sandbox`, so opening it\n directly keeps the same opaque-origin boundary.\n- Markdown goes through the same sandbox as uploaded HTML.\n\nIf the app is restricted, anyone allowed through the Val Town access gate can\nupload, rename, and delete artifacts.",[],[206],"084d3e5b-7141-4487-98a9-1d5a73eff7ee","upload.client.ts","01a01be0-4032-74fe-b778-9054966e8bd4","01a01be0-4032-74fe-b778-9660538c09f1",["D",1787174076294],"// Drag-and-drop / file-picker uploader for the dashboard, plus a small\n// confirm() for delete forms.
