# Inline Subreddit Color Popover — Design, Plan & Implementation

**Date:** 2026-08-26
**Task:** Design, plan, and implement an inline color-override popover for subreddit badges, allowing users to set per-subreddit colors directly on the page.

## Changes Made

### Commits (6bf7935..210676e)

4. **`565f039`** — feat: popup per-subreddit overrides with mode-aware light/dark toggle
