Hi 👋 — I’d like to work on #320: Light Theme Support (Experimental Toggle).

I have experience implementing theme systems using Tailwind and CSS variables. I’ll add a light/dark theme toggle with persistent preference via localStorage, ensure accessibility compliance, and keep styling consistent across components.

I’ll scope changes cleanly in the ui/light-mode-support branch and follow existing design patterns.
