One card per systems page, titled with the manufacturer and listing its consoles as far as three lines hold. Rendered once and committed like the platform cards.
Diagram text reads at 14 px in the column, boxes take the height of their lines, paths are mono on a line of their own. One setup count for every page. Wiki pages expand install commands into system tabs, an options table read from install.py, and keep example hashes out of search.
scripts/sitediagrams.py writes the explainer, install flow, verification modes, MinUI card, pipeline and data layer diagrams as inline SVG from the registry, the platform files, the install manifests and the pipeline step list. A page asks for one with an image comment, which the decoration pass resolves. The two mermaid diagrams of the architecture page are replaced, so no page loads mermaid from unpkg.
Platform logos and system icons are copied once by fetch_site_images.py with their source and owner recorded, and the build rewrites the remote links to the copies. validate_site refuses an image from another host. Three registry logos named a personal avatar instead of the project's (RomM, ROCKNIX, MiSTer FPGA) and MyMinUI's was a GitHub identicon, now dropped.
One 1200x630 sharing card per section, a 404 page with search and the two entry pages, and a list of screenshots that need a real device.
