"""Pin the pure hexToRgb helper (static/js/color/hex.js).
|
|
|
|
Driven through `node --input-type=module` (same approach as test_compare_js.py);
|
|
skips when `node` is not installed.
|
|
|
|
Regression: theme.js parsed hex with fixed substring(0,2)/(2,4)/(4,6) slices, so
|
|
a 3-digit shorthand like "#abc" produced NaN channels (the color picker already
|
|
expanded shorthand correctly — theme parsing did not).
