- Brainstorm page: orange → brand-accent throughout
- PageEntry animation component added to key pages
- Floating AI button: bg-brand-accent instead of hardcoded black
- i18n: all 15 locales updated with new AI/billing keys

+  Mac is tuned up and ready to jam! Your Suno Band Manager module is installed.
+  Run this setup again any time to reconfigure settings.
+
+  Get started by talking to Mac (your Band Manager) or jump straight into any skill:
+  Create a song, manage band profiles, build style prompts, transform lyrics, or refine your Suno output.
+
+  **Multi-machine workflow?** This module ships pack/unpack scripts for moving
+  your songbook, voice files, and WIP between machines without git. Run
+  `bash scripts/pack-portable.sh` (or `pack-portable.ps1` on Windows) when you
+  want to sync. Marketplace-install users may need to copy these from the
+  GitHub repo first — see INSTALLATION.md "Multi-Machine Sync".
