- Hash the lowercased description (matching the case-insensitive scoring) so the same archetype text picks the same preset regardless of case. - Thread the character name through provisionVoice -> stepfunProvision as the hash salt, so two characters that share archetype keywords spread across the top-N candidate presets instead of collapsing on one voice. Xiaomi path is unaffected (voicedesign mints a unique clip per call).
