## Summary Follow-up to #36613 (full Ember app embed mode). When an embedd…ed page's title can't be parsed by `ruby-readability`, `TopicEmbed.import` creates a topic with a blank title and slug. This causes: - **Redirect loop**: `Topic.url` generates `/t//123` (double slash), and `TopicsController#show` endlessly redirects trying to add the missing slug - **Broken topic**: The topic has no title or meaningful content ### Changes - **`topic_embed.rb`**: Fall back to the embed URL as the topic title when the parsed title is blank - **`topic.rb`**: `Topic.url` omits the slug segment when slug is blank (`/t/123` instead of `/t//123`) - **`topics_controller.rb`**: Skip canonical slug redirect when the topic has no slug (nothing to redirect to)
