Side B makes a focused behavioral fix to the Reddit importer by skipping stickied/pinned posts during subreddit parsing, preventing unwanted permanent entries from being imported, and adds a regression test covering both the `stickied` and `pinned` fields. Side A fixes UI highlighting/orientation issues and adds several tests, but much of the patch is presentation and styling changes, making its lasting impact somewhat narrower than the importer correctness fix.
