+- 2026-08-17: One wording for an empty password field on every screen that asks
+  for one. The private key export screen said "Password is required." where the
+  other five say "Please enter your password.", the same one-condition-two-
+  wordings split that [#172](https://git.eeqj.de/sneak/AutistMask/issues/172)
+  closed for a rejected password. Strings only, no behaviour change.
+  `tests/passwordMessages.test.js` now pins the empty-field guard per call site
+  as well as the decrypt handler, anchored on the `decryptWithPassword` sites so
+  the wallet-creation screen — where an empty field means a password being
+  chosen, a different condition — stays out of the set. Every error container
+  measured at a 360px viewport in the pinned Playwright container: the export
+  screen's container holds at 20px with the following section at the same offset
+  for the old string, the new string and the empty reserved state
+  ([#265](https://git.eeqj.de/sneak/AutistMask/issues/265)).
