[!] (plugin less) Error: Unrecognised input

[JasonKleban]

Even on an empty or trivial "grid.less" with no byte order mark, I'm getting this output from rollup using rollup-plugin-less (and rollup-plugin-less-modules in case that's the source, but I doubt it?)

[!] (plugin less) Error: Unrecognised input
src\content\styles\base\grid.less

even with this content:

html { }

What else can I check for?
