- Git/DevOps tools (GitPython): clone, status, diff, log, blame, branch,
  add, commit, push, pull, stash — wired to Forge and Helm personas
- Image generation (FLUX via diffusers): text-to-image, storyboards,
  variations — Pixel persona
- Music generation (ACE-Step 1.5): full songs with vocals+instrumentals,
  instrumental tracks, vocal-only tracks — Lyra persona
- Video generation (Wan 2.1 via diffusers): text-to-video, image-to-video
  clips — Reel persona
- Creative Director pipeline: multi-step orchestration that chains
  storyboard → music → video → assembly into 3+ minute final videos
- Video assembler (MoviePy + FFmpeg): stitch clips, overlay audio,
  title cards, subtitles, final export

Also includes:
- Spark Intelligence tool-level + creative pipeline event capture
- Creative Studio dashboard page (/creative/ui) with 4 tabs
