 ### Changed
 
+- docs: [guide.md](docs/guide.md) reorganised into **Installation**, **Instance
+  administration**, and **Domain administration** — DNS setup, operations,
+  rate limiting, and backup sections follow the instance/domain boundary
+  instead of mixing them. **Installation** now reads Ports → Local trial →
+  Initial setup → Full deployment (with the fixed image tag nested under it) →
+  Environment variables → Reverse proxy; the step-by-step production deploy and
+  per-proxy TLS commands move here from README's "Reference deploy" (README
+  keeps a short pointer). Internal (non-operator) environment variables move
+  to [architecture.md](docs/architecture.md) § Configuration; the guide keeps
+  a one-line pointer. **Full backup and restore** gains worked commands for
+  in-place restore, move-to-a-new-host, and encrypted-backup decrypt-first,
+  plus the version-mismatch error text. README anchors updated for the new
+  headings. No behaviour change.

 ## [1.2.5] - 2026-08-13
 
 Rate-limit form polish after 1.2.4. Upgrading is a tag bump; no migration.
