projects: add The Mirror pull-through registry case study; wire cover art for both learn-site projects
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.

# Project cover prompts - bztmon.com
Two covers to generate: **The Exploded Cluster** and **The Mirror (pull-through registry)**.
Paste the block below the `---` for each one into Gemini / Nano Banana 2, generate ~4
variations, curate against the reject list, then process per "After generating".
Aspect: **3:2 landscape** (existing covers are 1600 x 1074).
---
## House style block (already inside each prompt - do not paste separately)
The site's covers are dark isometric hero renders: matte dark hardware, cyan and magenta
edge light, a subtly circuit-etched ground plane, thin atmospheric haze, one small four-point
sparkle highlight, and generous empty space on one side so the card's title text has room.
Unlike the learn-site scene plates, covers MAY have a ground plane and atmosphere - they are
never sliced or animated.
## Reject checklist (per candidate, before you keep it)
- [ ] any text, letters, numbers, logos or UI chrome anywhere in the frame (reject hard)
- [ ] subject clipped by the frame edge, or centred so tightly there is no negative space
- [ ] colours drifting warm - the palette is cyan/magenta on near-black, no orange or gold
- [ ] photographic realism or stock-render gloss (it should read as an illustration)
- [ ] busy background competing with the subject
- [ ] the two covers looking like the same object (they must be distinguishable as a pair)
## After generating
1. Keep the best of each, name them `exploded-cluster.png` / `mirror-registry.png`.
2. Convert and place (from the repo root, on the box with the site checkout):
```
# full-size cover: 1600px wide
ffmpeg -y -i exploded-cluster.png -vf "scale=1600:-2" -q:v 80 public/covers/exploded-cluster.webp
ffmpeg -y -i mirror-registry.png -vf "scale=1600:-2" -q:v 80 public/covers/mirror-registry.webp
# card thumbnail: 640px wide
ffmpeg -y -i exploded-cluster.png -vf "scale=640:-2" -q:v 80 public/covers/thumb/exploded-cluster.webp
ffmpeg -y -i mirror-registry.png -vf "scale=640:-2" -q:v 80 public/covers/thumb/mirror-registry.webp
```
3. Both project files already reference these names (`cover: "exploded-cluster"`,
`cover: "mirror-registry"`), so the cards pick them up on the next build.

# PROMPT 1 - The Exploded Cluster
Dark isometric technical illustration in a cinematic sci-fi engineering style, 3:2 landscape.
Near-black background, hex #070b14, with a faint dark circuit-etched ground plane beneath the
subject and a thin drift of atmospheric haze in the upper right. Matte dark metal and smoked
glass surfaces with glowing neon edge lighting: primary cyan #3fbaf5, secondary magenta
#e879f9, cool white rim highlights. Even studio lighting, no lens flare, no depth-of-field
blur. ABSOLUTELY NO text, letters, numbers, logos, labels, arrows or UI elements anywhere in
the image - surface markings must be abstract geometric patterns only.
The subject: a single machine caught mid-explosion, its layers separated vertically like an
engineering teardown diagram, floating apart with clear gaps of void between them. From the
bottom up: a heavy dark chassis base with cyan-lit vents; above it a thick slab housing rows
of small identical cells; above that two thin translucent glass sheets etched with fine
circuit tracery, glowing faintly cyan; and at the top, held well clear of everything else, a
small bright magenta-lit cube - the smallest and most luminous part, clearly the payload the
whole machine exists to carry.
The parts hover in stable formation rather than flying apart violently - a considered
teardown, paused for inspection. Composition sits left of centre, leaving open dark space on
the right third of the frame. One small four-point white sparkle highlight in the lower right,
far from the subject.

# PROMPT 2 - The Mirror (pull-through registry)
Dark isometric technical illustration in a cinematic sci-fi engineering style, 3:2 landscape.
Near-black background, hex #070b14, with a faint dark circuit-etched ground plane beneath the
subject and a thin drift of atmospheric haze in the upper left. Matte dark metal and smoked
glass surfaces with glowing neon edge lighting: primary cyan #3fbaf5, secondary magenta
#e879f9, cool white rim highlights. Even studio lighting, no lens flare, no depth-of-field
blur. ABSOLUTELY NO text, letters, numbers, logos, labels, arrows or UI elements anywhere in
the image - surface markings must be abstract geometric patterns only.
The subject: a wide, low, heavily-armoured way-station machine sitting on the ground plane,
right of centre - a bunker-grade cache with a glass-fronted shelf running along its face,
holding a row of small identical luminous cyan bricks in cold storage. Its face has a single
broad output aperture ringed in cool white light, aimed left.
Above and behind it, arranged in a loose arc receding into the haze, five small dark intake
pods at clearly diminishing scale - each a compact rounded capsule with one cyan-lit aperture,
each floating alone with generous void between them, none touching the main machine. They
read as five distant sources feeding one local shelf.
Below and left of the way-station, close to the ground plane, a single luminous cyan brick
hovers in mid-transfer - small, bright, clearly in motion toward the viewer's side of the
frame, the one thing the whole arrangement is delivering.
Composition sits right of centre, leaving open dark space on the left third for title text.
One small four-point white sparkle highlight in the upper right, far from the subject.
