Per-garden public read-only link: unauthenticated GET /api/v1/public/gardens/:token (no requireAuth, no OIDC), owner-only enable/rotate/disable, and a /g/$token page rendering GardenCanvas read-only. Review fixes: redact plant owner ids, Cache-Control: no-store, 400 on malformed body, shared resetTransient store action. Closes #41. Co-authored-by: Steve Dudenhoeffer <[email protected]>
