# Research: Tailwind & CSS Variables Theming

## Hypothesis
We can keep CSS output small while supporting dynamic theming via CSS variables and Tailwind utilities.

## Questions
- Mapping CSS variables to Tailwind utilities without bloating CSS
- Safe patterns for dynamic classes and purge
- Runtime theme switching performance cost

## Method
- Prototype theme tokens and a toggle; inspect CSS size

## Acceptance
- Minimal CSS growth; smooth theme switching

## Deliverables
- Token design, Tailwind config guidance, sample components
