+# Scene prompt - Appendix: the dependency ledger (optional STILL - three supporting cast)
+
+This page is DOM-only by design; this hero is OPTIONAL dressing. It is a STILL - never
+scrubbed, never sliced - so composition matters more than separation mechanics, but the
+house contract stays so it sits beside the arc scenes as one family. The three objects
+deliberately ECHO silhouettes from the arc heroes: the etched crystal slab (Course VI's
+repo), the armoured vault cube (Course VI's secret store), the squat way-station block
+(Course VII's mirror). Curate for family resemblance.
+Generate ~4 at 16:9, curate with the reject checklist, save to disk for pickup.

+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 calm museum-piece portrait of three machines in a loose triangular
+arrangement, each floating alone in void with generous space between them - three
+supporting pillars at rest, presented for inspection rather than caught mid-explosion.
+
+Upper left: a faceted crystal slab of dark glass, its surface etched with a fine
+branching lattice pattern glowing soft cyan - frozen forks of recorded history.
+
+Upper right: a small heavily armoured vault cube - layered dark plates, dense and
+sealed, with one thin amber-white glowing seam around its middle.
+
+Lower centre, slightly larger than the other two: a squat wide way-station block -
+heavy, low, cache-like, with a broad warm cyan glowing intake recess on one face and
+thick armoured sides.
+
+The three sit in quiet balance, none touching, none dominant, a matched set from the
+same machine world.

+## Build-side notes (not part of the prompt)
+
+- **Usage:** page header still for the dependency-ledger appendix - rendered ONCE,
+  static, no slice manifest, no scrub. WebP <=250KB (smaller than scene budget - it is
+  dressing, not a set-piece). If it never generates, the page ships DOM-only as
+  designed - this prompt is a nice-to-have, not a gate.
+- **Family check at curation:** the three silhouettes should read as the SAME objects
+  from the Course VI and VII heroes (repo crystal, vault cube, mirror way-station) -
+  reject candidates that invent new shapes, even pretty ones. The teaching point is
+  recognition: "you have met these three before."
+- **Legend mapping (alt text):** crystal "GitHub - where the desired state lives" /
+  vault "Azure Key Vault - where the secret values live" / way-station "zot - where
+  the fleet pulls from".
+- **Watermark:** Gemini sparkle bottom-right - strip before use (ffmpeg delogo).
