diksha78dev/FamilyVault ? reverse-engineered prompt

Build me a simple family document vault for Indian families that helps people store important papers in one place instead of losing them in WhatsApp chats.

I want a clean mobile friendly web app where someone can join a family group with a simple code, upload documents with a name and category, and search them later by name or category. Make it easy enough for elders to use on a phone browser without needing to install anything. Use the existing backend setup and wire up a nice frontend that feels simple, trustworthy, and easy to understand.

Please make the main flows work end to end, joining a family, uploading a document, and searching the vault. Keep the design straightforward and polished, with warm colors and readable text. If you need current setup details or docs, look them up online or check the repo and finish it in one pass as much as possible.
