# Spearfish Tender: the user's blueprint measured (exec'd by build_spearfish.py; plain Python, no bpy).
#
# Source: reference/user_blueprint.webp ("SUBMERSIBLE - ORTHOGRAPHIC RECONSTRUCTION", 1958 x 691 px), sent 2026-10-20 with
# "Create this blueprint as subtub tender 3d model in blender using MCP precisely accordingly take your time check as the
# referance image". Every number below is a pixel read off the original picture (4x zooms with rulers, reference/z_*.png,
# and dark-pixel runs per column). Image x is shared by the TOP, PORT SIDE and UNDERSIDE views (nose tip x 1136, stern
# face x 527, stern lugs x 522); TOP centre line at image y 157.5; SIDE view heights are image y (down = larger).
#
# Scale and axes (the Kazah's: nose to -Y, port +X, Z up, origin 9 cm behind the docking clamp's axis):
#   S = 0.0155 m per pixel  ->  9.50 m from the stern lugs to the nose tip, fin span 3.8 m (fits the moon pool well
#   12.3 x 6.3 m with more than the user's 1 m all round). Origin at image x 822, so the clamp axis (y -0.09) sits at
#   image x 828, the middle of the hull. Height: the hull top (image y 342.5) at z 0.97, low enough that the docking
#   clamp's claws (lowest point z 1.24) pass 15 cm over the dorsal rails (image y 334.5 -> z 1.094).
#
# Where the five views disagree (an AI-drawn sheet), the choice made:
#   * big fins: TOP/UNDERSIDE give the planform, FRONT/REAR show them edge-on as a thick ribbed root, a rod and a round
#     disc. Built as the planform fin, low on the flank (FRONT: 0.76 of the height down -> image y 415), with a ribbed
#     actuator at the root (the SIDE view's ribbed "gills") and a small round lamp pod on the outer forward corner.
#   * antennas: TOP and SIDE show whips raked aft from two small stern pods; FRONT/REAR draw one central mast. The two
#     pods with whips are built (TOP is the most detailed view).
#   * canopy lower edge: SIDE says image y 429, UNDERSIDE and FRONT show the glass reaching further under: set at 434.
#   * stern grille: SIDE shows it under the stern lip, TOP on the aft slope, REAR as a hatch with vents: the end face
#     carries the hatch and slots, the aft slope a small three-slot vent.
