// === BUILD PLAN ===
// Style: planetary exploration rover (Curiosity/Perseverance family), scale ~1 block = 20cm
// Footprint: 25 long (X) x 19 wide (Z) incl. solar deck; centre (32,32); pad top Y=10, wheels rest Y=11
// Height: wheels Y11-17 | chassis Y17-20 | solar deck Y21 | mast head Y29-31
//
// SIDE SILHOUETTE (X horizontal, front = -X):
// ___________________ mast + camera head
// ____|########## ####|___ deck Y21
// | arm |##CHASSIS##| RTG | chassis Y17-20
// \ (O) (O) (O) wheels r=3, x = cx-8, cx, cx+8
// v ~~~~~~~~~~~~~~~~~~~~~~ ground Y10
//
// FRONT SILHOUETTE (Z horizontal):
// ==========DECK==========
// | white chassis |
// (O) (O) wheels at z = cz-6 / cz+6
//
// MATERIALS PLAN:
// chassis : noisePalette white_concrete(52)+light_gray_concrete(30)+iron_block(18)
// — WHY: pale body reads bright against red ground, subtle panel noise
// foil : gold_block + yellow_terracotta band, PROTRUDING 1 block on both flanks
// — WHY: thermal-blanket accent + real facade relief on a small volume
// wheels : black_concrete/polished_blackstone alternating tread (cleats) + iron hub
// — WHY: dark value anchors the silhouette, checker = grousers
// deck : blue_concrete field + light_blue cell lines + gray_concrete frame
// mast/arm: light_gray_concrete + iron_block, drawLine struts (rocker-bogie)
// ground : patches red_sand(40)+terracotta(24)+red_terracotta(21)+granite(15), boulders + wheel tracks
// Rooms: N/A (vehicle — no interior)
