I already have a functioning site; now I need two concrete upgrades. First, a straightforward email-and-password login system. It must cover registration, secure hashing, session handling, and a simple “forgot password” flow. I do NOT want any social-media or single-sign-on hooks—just the classic form-based approach that fits seamlessly into the design I have. Second, I’d like to introduce a small game-style feature. Picture a grid on the page: when a logged-in visitor clicks any square, the page should instantly display every picture uploaded by all users—pulled dynamically, laid out responsively, and ready for quick pagination or lazy-load if the dataset grows. Deliverables: • Cleanly integrated auth module with sign-up, login, logout, and reset. • Grid component wired to the database so one click reveals the full user photo collection. • Brief hand-off notes: setup steps, key files changed, and where to extend the code. I’ll provide repo access and clarify my current stack once we connect; your task is to plug these features in without disrupting existing pages and styling. If this sounds clear, let me know your timeline and any quick questions so we can get started.
