Migration script ready when you are. Touches 218 files; nothing structural. The big one is the color.brand → color.accent rename across surface, ink, and semantic layers.

Started drafting the v0.6 token spec. Open questions:
1) Should we keep the numeric surface ladder?
2) Where do mention colors live — semantic or brand?
3) Dark theme aliases — explicit map or computed?

One thing I learned from the last migration — don't touch color.surface.canvas in the same PR as the role rename. We did that in v0.4 and it was hell to bisect.

For the launch checklist — the token migration in #design-systems blocks the marketing site refresh. Sequencing matters: ship tokens, wait a day for any rollback, then deploy site.
