// why a language?

Layouts today are tied to specific tools and resolutions.

m0 makes layout portable — same string, any renderer, any size.

m0 makes layout testable — validate, diff, and compare in O(N).

m0 makes layout generatable — programs produce layouts, not people.

// the language

1 / F tile (rendered content)

0 / > passthrough (donates space forward)

- null (intentional gap)

N() column split

N[] row split

X{Y} overlay

2(F,F) → two columns

3[F,F,F] → three rows

2(F,3[F,F,F]) → nested layout

3(>,F,F) → first tile gets 2/3 width

3(F,-,F) → two columns with a gap

Programmable visual composition.

m0 layouts compiled to deterministic ffmpeg render plans. Template libraries. Batch generation. Cross-platform output.
