Space Haven Planner
Feedback from user:
"""
That's a good looking and very useful tool, but I think your canvas sizes are wrong.
Each unit of a canvas is 28x28 with a 1 square border you can't build in, so a 1x1 would be 26x26 buildable squares. When combining into a larger canvas, the adjacent border squares become buildable, so a 2x1 is (28
2 - 2) = 54x26 and a 3x1 is (28
3 - 2) = 82x26.

Order: 1/16
Impact: High
Estimate: M
Tags: priority:P0, core, presets
Summary: Correct canvas/preset dimensions to match Space Haven so planning + save import are accurate.
Notes:
  • Current grid presets assume 1 unit = 27 tiles (e.g. 1x1=27, 3x1=81).
  • Save imports use ship sx/sy directly; sample save fixture includes a 56×56 ship which does not fit any current preset (largest is 81×54).
  • Likely mismatch between “buildable area” vs “full canvas including borders”. Need to confirm correct game dimensions and decide representation before changing presets/migrations.
