Adds mirror-registry as a featured project (order 26, beside The Exploded
Cluster) covering the zot deployment, the bootstrap and auth circular
dependencies, and the retention/revalidation behaviours that corrected the
first published write-up. Adds the cover: field to exploded-cluster (it had
none, so the card rendered imageless) and stages public/covers/image.md with
the generation prompts and processing steps for both covers.
The inline SVG thumbs were placeholder-grade next to real art. Cards now use
a 640px mini of the same cover (9-22KB), object-fit cover with a slow hover
zoom, and a corner scrim so the DOSSIER tag stays legible over the brighter
frames. Falls back to the sketch for any project without a cover.
Six generated covers wired in via an optional cover key - 2528x1696 sources
optimised to 1600px webp, 49-144KB each. They sit on the page background
rather than the diagrams' light card, since the art is already generated in
the site palette on near-black. Cover carries the story at a glance, the
diagram still carries the architecture below it.
