+### Full Aiden Audio Regeneration
+
+Captured on 2026-07-09 after review: the second male voice, Voicebox profile `Aiden`, sounded better than the Adolfo cloned voice for this storybook narration. All 21 app pages were regenerated with Aiden using paced performance text: line breaks, ellipses, dialogue separation, and slower emotional phrasing to avoid glued-together sentences.
