// === BUILD PLAN ===
// Subject: crewed DSV on an abyssal shelf. Bow (glass pod) faces +Z toward the camera.
// Retrieval: search_docs related -> "Balloon/Envelope Shapes" gives the ELLIPSOID SHELL formula
// dx^2/rx^2 + dy^2/ry^2 + dz^2/rz^2 <= 1 with an inner test -> hull is HOLLOW BY CONSTRUCTION
// (no carving), so the pressure cabin exists for free. Proportions rule: rz ~= 2-3x rx.
// Also routed: fantasy-scifi Engine Section (concentric thruster rings + glow core),
// Cockpit Design (iron-framed glass, stone_button dash, lever throttle, stair seats, end rods),
// interior-design Chandelier + Hidden Floor Light, build-notes Empty Interiors (furnish it).
//
// Envelope: rx=5, ry=5, rz=13 centred (24,18,30) -> 27 long, 11 wide, 11 tall
// Pod: sphere shell r=5 at (24,18,47); the z>=49 cap is BUILT IN GLASS so the viewport reads outside.
// Y levels: seabed Y6 | skids Y8 | hull belly Y13 | axis Y18 | deck Y16, walk Y17 | tower top Y27 | mast Y30
//
// SIDE ELEVATION:
// mast|
// (tower) ___
// [O]==<<<<<##########################>>>>>===( GG ) GG = acrylic nose cap
// [O]==<<<<<##########################>>>>>===(_GG_)
// \skid========strut========skid/ \arms->[basket]
// ~~~~~~ pale sand + rocks + glass sponges + deployed lander ~~~~~~
//
// MATERIALS PLAN:
// hull : yellow_concrete(58)+yellow_terracotta(24)+honeycomb_block(18) above the boot-top
// boot-top: black_concrete ring at the widest belt WHY: a hard value line makes the ellipsoid read as a HULL
// belly : white_concrete(58)+light_gray_concrete(28)+iron_block(14)
// chevrons: orange_concrete / white_concrete alternating bands on the stern quarter (safety livery)
// pod : light_gray_concrete/iron_block shell, light_blue_stained_glass nose cap, iron_block frame ring
// engines : Engine Section palette - iron_block/gray_concrete rings, sea_lantern + shroomlight core
// arms : orange_concrete/orange_terracotta, iron_bars rams, polished_deepslate wrists
// seabed : sand/gravel/clay/white_terracotta patches, deepslate+basalt boulders, bone_block sponges
// Cabin: deck Y16, pilot station at the pod (stair seats + button dash + lever), science bay,
// sea-lantern-under-carpet floor glow, chandelier-style hanging lantern, crates. Ladder up the tower.
// PROCESS: DIRECT, shell-first (ellipsoid + sphere shells), then deck, then fittings.
