+Catalan (`ca`, Català) translation for SnappyMail. A complete linguistic pass
+was applied on 2026-10-16; see [review notes](REVIEW.md). Further corrections
+from Catalan-speaking users are welcome.
+
+Existing translations were adapted from RainLoop's official Catalan resources:
+https://github.com/RainLoop/rainloop-webmail/tree/9bf8fa5b63d7e6871ee533126a7e1b1c85ee45b5/rainloop/v/0.0.0/app/localization
+
+SnappyMail-specific strings were translated for this contribution. Preserve the
+original MIT copyright and permission notice in `LICENSE-RainLoop` when reusing
+the adapted RainLoop texts. The translation includes user, admin and static
+messages, plus the relative-time fallback resource.

+# Catalan linguistic review — 2026-10-16
+
+Reviewed the full user, administration, static and relative-time resources
+against their English originals: 567 user entries, 140 administration entries
+and 7 static entries. This pass changes 210 entries (161 user,
+46 administration, 3 static), including typography.
+
+## Editorial criteria
+
+- Use the Softcatalà distinction between short imperative commands in buttons
+  (for example, *Desa*, *Xifra*) and the *vós* form when addressing users in
+  explanations, questions or instructions (*Introduïu*, *Seleccioneu*, *Voleu*).
+- Prefer consistent terms such as *desar*, *xifrar/desxifrar*, *conversa*,
+  *text sense format* and *emmagatzematge*. Preserve proper names such as Sieve.
+- Correct semantic errors, not only spelling: `STOP_LABEL` must stop further
+  processing, `LABEL_UNREAD` marks messages as unread, and the domain allow-list
+  describes permitted **users**, not domains.
+- Distinguish read/display receipts from delivery receipts. Preserve all message
+  variables, including `%READ-RECEIPT%`.
+- Remove inherited RainLoop product references from SnappyMail interface text.
+- Preserve JSON keys, technical flags, placeholders and required HTML structure.
+  Use consistent apostrophes and quotation marks in displayed Catalan text.
+
+## Representative corrections
+
+| Before | After | Reason |
+| --- | --- | --- |
+| No aturis el processament de les regles | Atura el processament de les regles següents | The previous wording reversed the action. |
+| No llegeixis els missatges seleccionats | Marca els missatges seleccionats com a no llegits | Describes changing the unread flag. |
+| Net | Text sense format | Correct meaning of the plain-text editor option. |
+| scripts de sedàs | scripts Sieve | Sieve is a protocol name. |
+| Emmagatzeatge | Emmagatzematge | Spelling correction. |
+| Llista de dominis… | Llista d’usuaris del domini… | The allow-list contains users. |
+| El RainLoop està actualitzat. | SnappyMail està actualitzat. | Correct product name. |
