+* **appkit:** **Breaking change:** markdown agents must live under `config/agents/<id>/agent.md`. Top-level `config/agents/*.md` is no longer discovered; migrate each file to `<stem>/agent.md`. The reserved folder `config/agents/skills` is ignored until per-agent skills ship.

+// `@supports (color-mix)` override that re-mixes in oklab over the oklch
+// palette token. Browsers that support `color-mix` (recent Chrome/Arc) take
+// the oklab path; older embedded Chromiums (e.g. Cursor's built-in browser

+// sRGB interpolation produce visibly different tints — especially against
+// the dark `--card` token — the same card ends up looking different in each
