+SDK text now binds explicit type roles, while deprecated UI typography classes carry their bundled Poppins family, allowing the document-wide font reset to be removed without mixed editor typography. `--wb-font-family` no longer rethemes built-in editor text; apply it explicitly to consumer-owned surfaces that need it.

 ## Typography
 
-`style.css` inlines Poppins latin 400 and 600 and references the remaining Poppins and Inter faces in the adjacent `assets` directory. Preserve that `dist` layout when copying the stylesheet. A Content Security Policy (CSP) that defines `font-src` must allow both `data:` and `'self'` or the origin serving those assets. No external font CDN is contacted at runtime, so the SDK still works behind consent controls and in air-gapped deployments.
+Built-in text uses bundled type styles: semantic `wb-text-*` roles on migrated surfaces and Poppins-backed deprecated classes on remaining UI primitives. `wb-text-code` uses Inter for token names and IDs; fixed-width editors retain a monospace family. `style.css` inlines the used Poppins faces and references the remaining Poppins and Inter faces in the adjacent `assets` directory. Preserve that `dist` layout when copying the stylesheet. A Content Security Policy (CSP) that defines `font-src` must allow both `data:` and `'self'` or the origin serving those assets. No external font CDN is contacted at runtime, so the SDK still works behind consent controls and in air-gapped deployments.
 
 Other weights, Inter, and non-ASCII glyphs use `font-display: swap` assets. They can briefly appear in the fallback font while the matching file loads; preload the relevant `.woff2` files when that flash of unstyled text (FOUT) is unacceptable.
 
-Override `--wb-font-family` to use a different face:
+`--wb-font-family` remains available for consumer-owned surfaces that opt into it; built-in roles do not read this variable:
 
 ```css
 :root {
   --wb-font-family: 'Inter', system-ui, -apple-system, sans-serif;
 }
+
+.my-workflow-surface {
+  font-family: var(--wb-font-family);
+}
 ```
 
-Provide the font yourself (via `@font-face`, `@fontsource/<font>`, etc.) — the SDK only consumes the variable.
+Provide any replacement font yourself via `@font-face`, `@fontsource/<font>`, or an equivalent local source.
