Record the operator-approved first render and the verified grade + true-peak
limiter results (TP -1.7/-2.7/-2.8 dBFS, I -16.3 LUFS) with commit references.

Phase 3 quality fixes for the highlight renderer (multi-clip FfmpegEditRenderer
left untouched):
- cinematicVisualFilter: replace the weak fixed eq with a deliberate filmic grade
(curves medium_contrast S-curve + teal-orange colorbalance + eq + unsharp +
vignette). Richer blue, warm highlights, tonal contrast. Still one uniform look;
beat/category-specific grading is future work (needs a validated grade enum).
- audio mix: add a brickwall limiter (alimiter limit=0.72) after loudnorm. The
first render clipped at 0.0 dBFS true peak; measured re-render now lands
-1.7/-2.7/-2.8 dBFS per highlight (all within the -1.5 dBTP gate), integrated
loudness -16.3 LUFS.
Test updated; mvn -o verify green (245 tests, 0 failures).

Replace the unusable audiocraft path (requires xformers, which has no Intel-Mac
build) with runtimes proven to work offline on this machine:
- music: transformers MusicGen (facebook/musicgen-small)
- sfx: diffusers AudioLDM2 (cvssp/audioldm2), resampled 16k -> 48k
- voiceover: Piper (unchanged), normalized to 48 kHz mono
The worker CLI contract and exit codes are preserved, so the Java
LocalAssetSynthesizer license gate and fail-closed behavior are unchanged.
Add tools/provision_local_models.py to materialize models into models/ from the
local HF cache with no network. Models and their license sidecars live under the
git-ignored models/ dir; both audio models are non-commercial (CC-BY-NC-4.0 /
CC-BY-NC-SA-4.0), recorded for later production review.
Add docs/cinematic-highlight-poc-plan.md tracking the PoC plan and milestones.
mvn -o verify: 245 tests, 0 failures/errors/skips (unchanged).
