v2 diagram: kube-apiserver (the only door), etcd (consensus truth), scheduler
(filter -> score -> bind), controller-manager (the loops). Five parts.

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: five distinct machines floating apart in the void, the internals of one
control room pulled apart for inspection.

Front and centre: a tall imposing gateway block - a monolithic dark metal doorframe with
a single bright cyan glowing vertical slot down its middle, clearly the only entrance to
the scene, the most commanding object in the frame.

Behind and below the gateway: a heavy squat vault - a dark armoured strongbox with
layered horizontal plates like sealed drawers and a deep cyan glow escaping from its
seams, visibly the most protected object in the scene.

To the left of the gateway: a precise instrument block - a slim dark machine with a
tilted glass top face showing an abstract geometric sorting pattern of cyan facets,
elegant and analytical.

To the right of the gateway: a compact engine block with several small circular recesses
on its face, each recess holding a glowing magenta ring, like a bank of idling rotary
mechanisms.

Above the gateway, small and off to one side: a little drifting cluster of three tiny
identical dark chips with faint cyan edges, minor satellites of the bigger machines.

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

- **Slice plan:** 5 polygons - apiserver gate, etcd vault, scheduler instrument,
  controller-manager ring bank, the chip cluster (spawned pods motif). Collapse draws
  everything in toward the gate (everything watches the api-server, nothing talks
  sideways); scrub opens to the hero. Clamp at hero.
- **Legend mapping (v2 terms):** kube-apiserver "the only door - authn, authz, admission,
  persistence" / etcd "consensus truth - quorum or nothing" / scheduler
  "filter -> score -> bind" / controller-manager "the reconciliation loops" / chips =
  Deployment -> ReplicaSet -> pods lineage.
- **Watermark:** Gemini sparkle bottom-right - strip with
  `bztmon-site/scripts/dewatermark.mjs` before slicing.
