Subject: [PATCH] fix: detect imported recipe language for Translate button
 (v0.33.1)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

URL import extracts content in the source page's own language (no
translation), but never recorded what that language was, so the
Translate button's "recipe.language !== my locale" check always saw
null and showed the button unconditionally. The extractor now returns
a detected ISO 639-1 language code alongside the recipe.

Photo import always writes in the caller's locale already (see its
langInstruction) but never recorded that either — now sets it
directly to locale since it's known, not detected.

 All notable changes to Epicure are documented here. This file is mirrored in-app at `/changelog` (and in the admin dashboard) via `apps/web/lib/changelog.ts` — update both together.
 
+## 0.33.1 — 2026-07-14 17:45
+
+### Fixed
+- URL-imported recipes never recorded what language they were actually written in, so the Translate button couldn't tell whether translation was needed — the importer now detects the source page's language, and photo import records the language it always writes in.

 ## 0.33.0 — 2026-07-14 17:35
