docs(i18n): clarify chrome-only scope — never translate user content

+## What we translate (and what we never do)
+
+**Translate: UI chrome only** — fixed labels, buttons, headings, placeholders,
+empty/loading/status states, tooltips, and app-generated default *labels*.
+
+**Never translate: user-authored content.** Meeting titles, tag names, notes, transcript
+text, search snippets, dates — these are bound straight from data (`item.title`, tag
+values, `s.text`, …) and stay exactly as the user wrote them. If a string comes from the
+user or the recording, it does not get a key.
+
+So "convert view X" always means "key its fixed labels", never "touch its content". Most
+views are mostly content with a thin shell of labels — MeetingsList, for example, is ~10
+fixed labels (search placeholder, empty states, filter/bulk-export labels) wrapped around
+a list whose rows are pure user data.
+
+> Caveat — the `"Untitled meeting"` **default title is generated in the Rust backend**, not
+> the frontend, so it never reaches `t()`. Localizing app-generated defaults is a separate
+> backend decision, out of scope for this frontend effort.
