Colossal Pangolin (guided, fixed)

// === BUILD PLAN ===
// Subject: COLOSSAL PANGOLIN (organic / creature), walking pose, ~80 blocks nose-to-tail
// Setting: red-earth savanna, termite mounds, flat-topped acacias
//
// SIDE SILHOUETTE (Z horizontal left=snout, Y vertical):
//   ........########........
//   ....############........      <- armoured back, banded scale rows (proud rims)
//   ..#####################..
//   .####################.####..  <- tail as long as the body, dragging
//   ..##..##........##..##.....   <- 4 short stout legs
//   ==========================    <- ground pad Y6, feet at Y7
//
// TOP SILHOUETTE (X horizontal, Z vertical downward = head to tail):
//   .......o.......      o = small narrow head + tapering snout
//   ......###......
//   ....#######....
//   ...#########...      widest at mid-body (rx 8)
//   ...#########...
//   ....#######....
//   .....####......
//   .......###.....      tail curves off to +X behind the animal
//   ........####...
//   ..........####.
//   ............##.
//
// PROPORTIONS (organic-builds rules): head ~1/5 of body height, legs SHORT and stout
//   (pangolin is low-slung), tail = body length, thick at base tapering to 2 blocks.
//   +Y is UP: dy>0 = armoured BACK (scales), dy<0 = soft pale BELLY. Checked.
//
// MATERIALS PLAN (what goes where + WHY):
//   scales : noisePalette brown_terracotta/stripped_dark_oak/packed_mud/moss  — WHY: olive-brown
//            keratin with blotchy variation, never monomaterial
//   rims   : dark_oak_wood ring PROUD by 1 every 3 stations                    — WHY: this is the
//            "overlapping scale armour" read; geometric relief, not just colour
//   belly  : light_gray/white_terracotta on the lower 1/3                      — WHY: pale soft
//            underside = the value contrast that makes the silhouette legible
//   claws  : blackstone taper on the FORELIMBS only                            — WHY: digging claws
//   ground : patches red_sand/terracotta/coarse_dirt + termite mound cones      — WHY: red-earth
