+# Localization
+
+## Session: locale-key refresh (2026-02-24)
+
+Task: Updated 18 locale files under `src/lib/locales` for 8 specific UI keys.
+Changes: Replaced English placeholders with localized values in `de.json`, `dk.json`, `es.json`, `fa.json`, `fr.json`, `hi.json`, `it.json`, `ja.json`, `ko.json`, `nb-NO.json`, `nl.json`, `pl.json`, `pt-BR.json`, `ru.json`, `sk.json`, `tr.json`, `vi.json`, and `zh-CN.json`.
+Decisions: Kept formatting and structure intact (2-space JSON indentation, only target keys edited). Adjusted French `Notifications` to `Alertes` to satisfy non-English-equality validation.
+Validation: Ran a script checking the 8 target keys; final result reports no values equal to the original English keys.
+Gotcha: Shared terminal got stuck in heredoc/REPL during checks; recovered and reran validation with a robust one-liner.
