Task (challenging): Create functionality to share Gomoku games as blog posts.
1) Shows the "Share to Blog" button with className '.share-to-blog-btn' in the Gomoku game after the game is finished.
2) When clicked, open a modal form (className '.share-modal') with title input (className '.title-input'), description input (className '.description-input'), submit button (className '.share-submit').
Go to home page ('/') after submitted.
3) In Blog Detail, detect if a blog contains a Gomoku game recording and display a "Replay Game" button (className '.blog-replay-btn').
4) When the replay button is clicked, show a modal (className '.blog-replay-modal') with the full game replay interface.
5) The replay interface should include the start play button (className '.blog-replay-start-play'), showing the current move number with className '.current-move'. There is an interval of 1000 ms between each move. 
Constraint: DO NOT use any third-party packages; ONLY React/MobX APIs are permitted; Use MobX to manage the logic.
