Replace the plain hard-cut white caption with a refined 48px caption, a soft drop
shadow, a thin subtle border, and a smooth alpha fade in and out (0.4s ramps)
within each overlay timeline window. Highlight renderer only; the multi-clip
renderer and overlay placement/safe-area logic are unchanged. Test added;
mvn -o verify green (246 tests, 0 failures).

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).

Activated with --spring.profiles.active=localpoc. Points only at pre-provisioned
local model paths (Piper voice, MusicGen, AudioLDM2), disables bootstrap
auto-start, uses heuristic visual analysis, isolates PoC input/output dirs, and
keeps render disabled + director approval required. Base/production defaults are
untouched.

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).
