Plate system upgrade shipped. Every edit is now a per-entry write (no more whole-array saves, so concurrent writers can't erase each other), bulk replaces keep ten versions of history, and gates moved server-side: passwords live in KV, set from the header when logged in, and the API refuses reads without them. New connective tissue: a registry of all plates powering the front door at /, log entry permalinks at /<slug>/log/<id>, photo attachments on log entries, a site-wide Atom feed, sitemap, llms.txt, and serve-time og tags. This wiki was rewritten to match - plate-guide.md is the contract.
