Summary

• VE-04: before this change, the recipes and sprinkles check (companion_errors) only looked at import declarations, so export … from, export *, require() and import() got past it with no error. It now uses the new module_loads helper, which finds imports, export … from, export *, require('…'), import x = require('…') and import('…'), and skips anything type-only. @vanilla-extract/dynamic is added to the list with its own message. That package assigns variables at runtime, which Devup UI does not keep ([전수조사] 결과와 개발 범위 (2026-09-30) #682).
• VE-02 (globalKeyframes(name, frames) per [전수조사/D] 흡수 라이브러리 기능: css prop, 컴포넌트 선택자, @emotion/css, VE·StyleX API #690) gets a targeted error, not an implementation. Devup UI names every keyframes by hashing its content (ExtractKeyframes → keyframes_to_keyframes_name), so a keyframes with a fixed global name has nothing to compile to. I also tested emitting it as globalCss({ '@keyframes fade': {...} }), but that object form flattens the frames into one at-rule with opacity: 0/.5/1, so it isn't usable without changing globalCss itself. Before this change the stylesheet run failed with TypeError: not a callable function. Now a globalKeyframes import from @vanilla-extract/css is a located error that names it and says to use keyframes(), or to opt the alias out. A real implementation would need fixed-name keyframes support in globalCss, which can be a follow-up.
• module_loads.rs is identical to the copy in fix(extractor): report Emotion code left at runtime as located errors #904, so the two PRs merge cleanly (checked with git merge-tree).
• Docs: the limitations table and the vanilla-extract migration page.

New build errors (while @vanilla-extract/css is aliased):

• `@vanilla-extract/recipes` / `@vanilla-extract/sprinkles` generates CSS that Devup UI does not compile … for re-exports, require() and import()
• `@vanilla-extract/dynamic` assigns variables at runtime …
• `globalKeyframes()` from `@vanilla-extract/css` is not compiled by Devup UI …
