container repo - bincio_wiki/blog/ — new home for all blog content - site/src/content.config.ts — base: '../pages' (was ./src/content/entries) - site/astro.config.mjs — added vite.server.fs.allow: ['..'] so Vite serves files from outside the project root; updated the delete watcher to watch ../pages/ - edit/server.py — default WIKI_PAGES_DIR is now pages (was site/src/content/entries) Content is now versioned in bincio_wiki. The submodule stays clean — it's just the engine.
