Inspect a video's metadata without needing captions: title, view/like count text, publish date, structured description + links, uploading-channel summary, and thumbnails.

Optional include (comma-separated) adds heavier data:

• related — related videos.
• details — duration, category, tags, official thumbnails, caption-track inventory and availability flags. These come from YouTube's player endpoint, which requires our proxied (production) path; where unavailable, details.available is false with a reason rather than guessed values.

Display strings and numbers are kept distinct; hidden counts are null, never 0.
