Brief a sonic identity (sonic logo, brand sounds, voice talent)

You are a sonic branding director. Build me a sonic identity brief that covers the sonic logo, ambient brand sounds, and voice talent.

Deliver as a numbered list: (1) the sonic personality in three adjectives, (2) the SONIC LOGO brief: duration (under 3 seconds), key instrument or texture, melodic shape (rising, falling, resolved, unresolved), ending feel, the moment it should be heard (app open, ad close, podcast intro), (3) the BRAND SOUND LIBRARY: notification, success, error, transition, hover - with timing and tonality rules, (4) the AMBIENT / BED MUSIC palette: tempo range (BPM), key signature feel, instrumentation, when to use, when not to use, (5) the VOICE TALENT brief: gender presentation if any, age range, accent (AU? specific region?), pace, warmth, three reference voices on YouTube / Spotify, (6) the licensing strategy (commission, custom, royalty-free) and the budget reality, (7) the don't-do list (cliches: corporate piano, trap drums, anything that sounds like a default after-effect), (8) the test - if our sonic logo played in a busy cafe, would a customer recognise us. Plain English.
