Determine future use for this repository

ACM brand guidelines are currently accessible via [acmutd.co/brand.pdf](https://acmutd.co/brand.pdf), which makes the purpose of this repository unclear. In the meantime, this repository's GitHub pages site has been set to redirect to [brand.acmutd.co](https://brand.acmutd.co).

I recommend having this repository focus on:
- [ ] Reusable brand assets
- [ ] Configuration files for implementation, including:
- [ ] Tailwind CSS
- [ ] Other custom CSS
- [ ] Custom components

No specific files or tests are referenced, only external links to acmutd.co/brand.pdf and the brand.acmutd.co redirect. Start by reviewing those targets and the repository’s current landing/docs and Pages configuration to confirm what is already published. Then inspect the repo structure for any asset, Tailwind, or CSS/component content and decide what should remain. Done when the repo has clear documented scope and guidance for reusable brand assets/config/components instead of the current ambiguous purpose.
