Critical: Use Real-ESRGAN ONNX (not UpscalerJS/TF.js) for upscaling,
mark Object Eraser as experimental, switch to Debian slim (not Alpine)
for HEIC/libraw/libjxl support, add libraw for RAW formats.
Significant: Revise Docker target to 700MB-1GB, add SSE progress events,
fix StorageAdapter to use streams, add API error schema, define SQLite
write concurrency model, add CORS/SSRF/rate-limiting specs.
Comprehensive PRD covering tech stack (Vite+React+Fastify+Sharp+SQLite),
37+ image tools across 9 categories, Docker deployment on port 1349,
UI/UX architecture, API spec, and development roadmap.
