 # FrameBridge website source
 
-The website implementation follows the project GPL-3.0-only license. Project video is delivered separately. Copy release.example.json to release.json, add the supplied conceptual preview to assets/framebridge-preview.mp4, then run python3 -I -S build_site.py and python3 -I -S qa_site.py. The generator reads ../source/docs/COMMAND-GUIDE.json in this source layout. Production signing metadata must be supplied by a maintainer; never fabricate fingerprints or signatures.
+The original visual design and renderer are retained. The main workflow is
+administration of a home Linux network by one human administrator. Compatible
+desktop access is an auxiliary tool.
+
+The canonical source repository is the existing GERANAS Gitea project
+https://framebridge.betancourt.one/git/gerardo/framebridge. CLOUD provides the
+existing HTTPS reverse proxy; GERANAS serves the website, downloads and APT
+repository. Do not substitute a static Git mirror or another hosting backend.
+
+Copy release.example.json to release.json, then fill it from the exact verified
+release inventory. Its three profiles are Debian 13 amd64/Python 3.13 (trixie),
+Ubuntu 24.04 amd64/Python 3.12 (noble), and Linux Mint 22.x amd64/Python 3.12
+(mint22). A preparing catalog offers no new download or installation commands.
+Use ready only after verifying all DEBs, corresponding source, dependency
+source archives, signatures, checksums and the official public fingerprint.
+Metadata describes release artifacts; it is not itself evidence that a public
+hostname is operational.
+
+Project media is delivered separately. Copy the approved original R4 MP4 and
+JPEG into assets under their original filenames. The renderer verifies these
+identities before a ready build:
+

+
+The approved animation and original music remain unchanged. The video is
+identified as a 0.3.1 conceptual demonstration; it does not claim to be a live
+recording of the current release.
+
+Run:
+
+    python3 -I -S build_site.py
+    python3 -I -S qa_site.py
+    python3 -I -S test_release_catalog.py
+
+The generator reads ../source/docs/COMMAND-GUIDE.json and requires its version
+to match the release. QA checks local links/assets, loopback HTTP, the guarded
+ready renderer with a disposable synthetic inventory, and syntax of all three
+APT setup blocks. The test fixtures never sign, publish or install anything.
+Perform final HTTPS, Gitea clone and isolated APT verification through the
+actual public domain before reporting publication complete.
+
+The website follows the project's GPL-3.0-only license. Third-party materials
+retain their own licenses and notices. Support is voluntary; the contact and
+PayPal account supplied by the project owner is gerardobh1128@gmail.com.
