"""
Loop Grid: a slanted desk with an 8 by 8 grid of lit pads, a row for each
element and a column for each loop, a big tempo knob, a covered lever that
throws the focus lock, and the bridge's stop button, activate button, light and
antenna. The bridge's board lives inside, on a printed tray.

Run from the cad/ folder:

    uv run loop-grid/model.py

It writes, for the site:
    site/public/files/loop-grid/stl/*.stl         cheeks, panel tiles and tray, laid flat
    site/public/files/loop-grid/loop-grid-stl.zip
    site/public/files/loop-grid/loop-grid.step    the whole desk, for editing
    site/public/files/loop-grid/loop-grid.glb     the 3D model shown on the page
    site/public/files/loop-grid/loop-grid-cad.py  this script, and console.py beside it
    site/src/content/instruments/loop-grid/drawings/loop-grid-render.svg

Coordinates as in set-list/model.py: X across from the left cheek's inside
face, Y front to back, Z up; u across and v up the slope on the panel.

The pads are four bought 4 by 4 boards with silicone keys, side by side under
one square window. All numbers are a first design, untested in print.
