Meridian Zero v0.1.0

A theme is just a set of CSS custom properties you override globally. Every colour, space and size in editorzero reads from a token (--ink, --paper, --ultra, --agent…). Re-skinning is editing those globals — no rebuild, no fork. Ship a curated theme, or paste your own :root{ } block. Humans and agents stay legible under every set.

The dispatcher routes every mutation through one transaction seam, so humans and agents converge on a single CRDT.
