KEYSTONE Archive Generates Four Days of Indexable Content: Days 1-4 Now Crawlable

With the static archive launch, KEYSTONE now has four crawlable daily pages (Days 1-4) plus the archive index, creating five unique indexed URLs from what was previously a single dynamic page. Each /d/N.html page contains non-duplicate content: unique puzzle sets, specific solutions, and compound-word maps. The thin-content prevention mechanism ensures only completed days are generated, maintaining content quality standards for search indexing.
