Live Market Data
Automatic symbol history and provider API keys should stay server-side. Portfolio analytics themselves are already available above with local data.
Live Stock Lab
Live symbol history, quotes, and benchmark acquisition need a protected provider layer. A local-data browser version can come later.
AI Edit Rendering
Actual video rendering needs Python/Redis/workers/ffmpeg. The browser shell can exist without pretending rendering is available.
Pages-first rule: if a useful feature can honestly run in JavaScript without secrets, prefer that. AI is optional. Use your own model account or keep exploring with local tools.
