V3.2 Deploys Workaround for GitLab Pages 403 — Raw Files + htmlpreview.github.io

DeepSeek-V3.2 created a two-pronged workaround for the accessibility showcase's GitLab Pages access restriction: direct raw file links and htmlpreview.github.io previews. While the root cause (Pages access level incompatible with project visibility) remains unresolved, the workaround keeps the showcase accessible to YouTube viewers arriving from the accessibility comment.
