In this update to CHOLA (CI), I focused on maximizing UI personalization and accessibility by engineering a fluid theme and language switching system. I built a dynamic glassmorphic interface that allows users to instantly toggle between an eye-strain-reducing Night mode and a clean Day theme, saving their preference natively to browser storage. Alongside the visual overhaul, I implemented a system-level dual-language pipeline that fluidly adapts formatting and input layouts between English and Tamil (தமிழ்), adjusting the underlying prompt behavior in real time so users can interact naturally in their preferred dialect.
