Dark technical exploded-view illustration in a cinematic sci-fi engineering style.
Solid near-black deep void background, hex #070b14 - completely clean: no stars, no grid,
no texture, no particles behind or around the objects. Matte dark metal-and-glass surfaces
with glowing neon edge lighting: primary cyan #3fbaf5, secondary magenta #e879f9 accents,
cool white rim highlights. Camera: fixed 30-degree isometric angle, subject perfectly
centered with generous empty margins on all sides. Even studio lighting, no vignette,
no lens flare, no depth-of-field blur. ABSOLUTELY NO text, no letters, no numbers, no
words, no code, no glyphs, no labels, no arrows, no callout lines, no UI elements
anywhere in the image - every surface marking must be an abstract geometric pattern
only. Every component is fully separated from its neighbours by generous gaps of pure
void - nothing touching, nothing overlapping, and no beams, cables, or connectors
spanning between the separated parts.

The subject: a small fleet of four machines floating in the void, mid-explosion.

At the top: one wide, flat command slab of dark brushed metal, clearly the authority of
the scene - a strong cyan glowing seam around its edge and a fine glowing lattice pattern
across its top face, hovering alone with a large gap of void beneath it.

Below it: a row of three identical compact worker blocks, evenly spaced with generous
void gaps between them - chunky dark metal cubes, each with a subtle cyan edge glow and
a single soft magenta accent line, visibly simpler and plainer than the command slab
above. All three share the same size and design, reading as interchangeable units.

The four machines are aligned as one formation pulled apart for inspection: one commander
above, three identical workers below.

## Build-side notes (not part of the prompt)

- **Slice plan:** 4 polygons - control plane, node 1, node 2, node 3. Collapse pulls the
  three nodes up and inward toward the slab (formation closes); scrub opens it to the
  hero layout. Travel clamps at the hero - no overshoot.
- **Legend mapping (v2 terms carried to DOM):** control plane "decides - holds truth,
  schedules, reconciles" / nodes "run pods" / the decide-vs-run split line. Terms:
  declarative intent, reconciliation loop, desired vs actual state.
- **Watermark:** Gemini sparkle bottom-right - strip with
  `bztmon-site/scripts/dewatermark.mjs` before slicing.
