I’ve fixed two issues: [FIX: unread dot not clearing for nested topics and never-opened topics - Pull Request #14 - VaperinaDEV/discourse-topic-preview-modal - GitHub](https://github.com/VaperinaDEV/discourse-topic-preview-modal/pull/14)

1. **Nested view:** `readPosts()` was delegated to core’s site-wide nested controller instead of the modal’s own `postRegistry`, so the per-post read-state dot was never cleared inside the modal.
2. **New topics:** only `unread_posts`, `unread`, and `new_posts` were reset, but the separate `unseen` flag that drives the new-topic dot wasn’t, so it remained visible in the topic list after the topic was read in the modal.
