# Mako Tender: the user's reference sheet measured (exec'd by build_mako.py; plain Python, no bpy).
#
# Source: reference/user_reference.webp (1448 x 1086 px: TOP, FRONT, SIDE, REAR), sent 2026-10-20 with "can you create me a 3d
# tender model that can be usable as an real asset in the descent vessel. try to create similiar from that referance picture.
# red line indicates where the the arm holder clips place so arms can hold the sub tub." Every number below is a pixel read
# off the original picture: colour runs per column (build/mk_runs.py, classes in reference/classes.png) and zooms with rulers
# (reference/z_*.png). TOP and SIDE share their image x (nose tip x 42, orange tail end x 888, tool cluster to x 952); SIDE
# heights are image y (down = larger), TOP lateral offsets are px from its centre line (image y 267).
#
# Scale and axes (the Kazah's: nose to -Y, port +X, Z up, origin 9 cm behind the docking clamp's axis):
#   * the clamp axis is the centre of the user's red loop in the TOP view, image x 292 (over the canopy's rear and the collar);
#     the origin 9 cm behind it is image x 304;
#   * S = 0.0075 m per pixel: the largest scale at which the whole Tender, fins and stern tools included, stays 1 m inside
#     the deck well at BOARD (the user's limit since the Manta). The well is an oval 6.3 x 12.3 m centred on the origin
#     (checks/well_tender_frame.json); at 7.6 mm/px the fin tips and the tool cluster come within 1 m. 6.8 m long overall;
#   * height: the hull top at the clamp axis (image y 672) at z 1.00, so the claws (lowest z 1.24) pass 0.16 m or more
#     over the collar and the holder clips stand on a short saddle (disc top z 1.15, the Spearfish's interface).
#
# The FRONT and REAR views are drawn about 1.4x larger than TOP/SIDE for the body but not for the fins (an AI-drawn sheet):
# they give section shapes and the fins' droop (about 60 deg below level), not sizes. Where views disagree, the choice:
#   * big fins: TOP puts the tips at image x 711, SIDE at x 600: built at x 640, lateral and height from TOP and SIDE;
#   * canopy: TOP and SIDE show glass right to the collar at the top, but the user put the holder clips there: the canopy's
#     top-rear is an orange hood (it continues the hood the FRONT view draws over the dome) that carries the clamp saddle,
#     and the hatch is inside the clips, as on the Kazah's hatch collar;
#   * the orange top shell's lower edge follows the SIDE view; TOP draws it narrower than any convex hull allows.
