Updated web/index.html and removed unused default-react logos

Editor assessment

The subject is a file-change list, index.html updated and unused default React logos removed, rather than a statement of purpose, which was presumably clearing scaffold leftovers during a rebrand or cleanup. Fix is a loose type for what looks like chore work, 'updated' is past tense, and no scope or body explains why the logos were removed or what changed in the HTML, so the reader supplies the motivation from the diff. Hygiene is otherwise acceptable. Understandable, honest, and mechanical, recording edits without explaining them.
