[MehranMarxian]

What changed and why

Adds v4d-next/: a build of the V4D viewer v0.6.0 (Atelier) for a smoke check before it replaces the live page. The live /v4d/ is not touched and stays at v0.1.0.

• v4d-next/ is built from the private V4D repository, branch claude/v060-atelier (MehranMarxian/V4D#7), with its apps/viewer/scripts/publish.mjs (VITE_BASE=/v4d-next/). Not hand-edited.
• Its index.html carries noindex, and no page links to it.
• CLAUDE.md, docs/SITE-OVERVIEW.md: one line each for the new folder. CHANGELOG.md: one line.

Once merged, Pages serves it at https://mehran-ahmadi.com/v4d-next/ within a minute or two.

How it was tested

Served this branch locally (python -m http.server 8899) and ran the V4D repository's scripts/check-published.mjs http://localhost:8899/v4d-next/ in headless Chrome on the real GPU (RTX 4070 Ti):

• the Viewer opens on Echo, on the walker (6,000,000 points);
• the Atelier opens a look on the demo subject (the dancer, 1,534,898 points, fetched from /v4d-next/demo/);
• it reports v0.6.0;
• no errors and nothing missing, except works/works.json, which is absent by design until a work is published.

/v4d/ still answers as before. Not tested: Safari, Firefox, a phone.

Risks and follow-ups

• Size: 75 MB added to the repository (two WebAssembly files, 27 MB and 13 MB, and the 34 MB demo block). It stays in the history even after the folder is removed.
• The demo block is a dancer generated with Kling AI 4.0 and lifted by ReLift: not a capture of a real person, and non-commercial (see v4d-next/demo/README.md). It is fetched only when opened in the Studio.
• The site's checks do not cover this folder (it is not a live page).
• After the smoke check, a second PR would replace v4d/ with the same build and remove v4d-next/.

Suggestions

1. After approving the preview, publish v0.6.0 to /v4d/ and remove /v4d-next/ in one PR.
2. Update the V4D story page (v4d-virtual-fourth-dimension.html) with one or two of the new images, once you have chosen the looks you keep.
3. Add a rule to site-checks.yml that fails a PR if a file over 50 MB is added, so a build can never exceed GitHub's limits by accident.
