refactor(docsite): remove XLE/XLO Layout DSL from the public playground#3283
Merged
Conversation
…ground
The XLE/XLO layout-expression tool now lives in the internal component
sandbox (apps/sandbox Tools → 'Layout DSL'), which is its intended home.
It had also been shipped in the public docsite playground (astryx.atmeta.com/playground);
this removes that duplicate so the layout DSL stays sandbox-only.
- drop the 'Layout DSL' SideNavItem + 'layout' LeftView and the XLEPanel pane
- delete the playground XLEPanel.tsx / xleExamples.ts
- delete the docsite generate-xle-{registry,tokenizer}.mjs build scripts and
drop them from the 'generate' pipeline
- remove the now-unused gpt-tokenizer devDependency and the
public/xle-tokenizer.mjs gitignore entry
The sandbox copy (apps/sandbox/src/app/(sandbox)/pages/layout-dsl) is
self-contained and unaffected.

The docsite no longer depends on gpt-tokenizer (XLE tokenizer moved to the sandbox), so remove it from the docsite importer in the lockfile. The package is still resolved via packages/cli, so the package/snapshot entries stay.

What
Removes the XLE/XLO Layout DSL tool from the public docsite playground (
astryx.atmeta.com/playground). The layout-expression tool already lives in the internal component sandbox (apps/sandbox→ Tools → Layout DSL), which is its intended home — it had been duplicated into the public playground and "got pushed out." This keeps it sandbox-only.Why
Per the thread: the XLO playground was meant to live in the internal sandbox first, not the public playground. The sandbox copy is complete and self-contained; this PR just removes the leftover public-playground duplicate.

The sandbox implementation (
apps/sandbox/src/app/(sandbox)/pages/layout-dsl) is untouched — it has its own self-contained page, generate scripts, tokenizer handling, and registry. Verified no dangling references to the deleted files remain in the docsite.
