The pale four-point star bottom-right in seven project covers and four blog
heroes is the image generator's watermark, not house style. Scrubbed via
delogo and verified numerically (peak luminance in the mark's box drops from
~100-255 to under 30 in every file); thumbnails regenerated from the cleaned
masters. The cover prompt file wrongly described the mark as part of the house
look and asked new generations to include one - corrected, with a reject-list
entry naming the mark and its usual position.
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.
