## Overview

AlecSync is a Flask social network: members register or sign in, then discover and publish posts, interact with other members, and use private messaging. Domain blueprints handle those workflows through forms and shared SQLAlchemy models; server-rendered pages provide the core experience, with JSON endpoints and browser JavaScript enhancing selected interactions. The README documents capabilities beyond the sampled excerpts; links to those features are included only where documented, and unsampled implementation details are not inferred.

Main entry points: [`app/__init__.py`](https://github.com/alexalkhatib/alecsync-social-platform/blob/main/app/__init__.py) (App factory), [`app/models.py`](https://github.com/alexalkhatib/alecsync-social-platform/blob/main/app/models.py) (Domain models), [`app/posts.py`](https://github.com/alexalkhatib/alecsync-social-platform/blob/main/app/posts.py) (Posts and replies), [`app/users.py`](https://github.com/alexalkhatib/alecsync-social-platform/blob/main/app/users.py) (Profiles and settings)
