Spent this session tracking down a login bug that had been bugging me - turns out a security header on my site was quietly blocking the auth popup from talking back to the app, so users had to refresh after signing in for it to actually register. Fixed that, then made the upload box actually prompt you to sign in instead of just… doing nothing when you’re logged out. After that I gave the whole site a real visual identity instead of the generic AI-startup look it had - leaned into a blueprint/drafting theme since it fits an architecture tool, ditched the soft gradient blobs for a grid background, and rebuilt all the buttons with a chunky neo brutalist shadow style. Also added dark mode from scratch - toggle in the navbar, remembers your preference, styled across every page - and caught a dumb bug along the way where one page’s card was using the wrong color variable and turned into an unreadable white blob in dark mode. Fun catch.
