Improvements to mdbase.dev across search, page copies for text tools, app screenshots and the homepage.

Homepage

• Leads with what mdbase does: keeps records as Markdown files, syncs them between devices and serves them to apps on any device.
• Shows a real TaskNotes screenshot beside the task's Markdown file.
• New "Open it from any device" chapter and particle scene (serve): apps on a phone or in a browser reach the collection through mdbase while your computers are off.
• The Cloud copy vs Private chapter and the field-merge scene are removed. Private is now a pointer to the security page, and field merging is a sentence in the Sync chapter.
• Beta notice under the title; status, source and developer facts at the end. No Obsidian mention.
• The fixed header fades into the sky, which removes the hard dark edge.

Site

• Pagefind site search in the header, opened with / or Ctrl/Cmd+K.
• index.md beside every searchable page, plus /llms.txt and /llms-full.txt (scripts/build-llms.mjs), built in CI, deploy and deploy:dev.
• Framed light and dark screenshots of TaskNotes, Editor, Reader and Writer (AppShot), used on the homepage and the Apps page.
• Apps page: removed the "How apps reach a collection" and "Try without an account" sections, and the demo links.
• SDK pages say "beta on npm" and recommend pinning an exact version.
• Social card is JPEG and textures are WebP.

Checks

• pnpm test passes, including the homepage scene tests at six widths, the build, the search index and the link check.
• Checked in light and dark at desktop and phone widths on https://mdbase-dev.pages.dev/.
